Acciones y filtros para desarrolladores

El plugin ShortPixel Image Optimiser llama a las siguientes acciones y filtros:

do_action( 'shortpixel_image_optimised', $post_id );

tras una optimización correcta;

do_action("shortpixel_before_restore_image", $post_id);

antes de restaurar una imagen desde una copia de seguridad;

do_action("shortpixel_after_restore_image", $post_id);

después de una restauración correcta;

For version 4.22.10 and earlier:

apply_filters("shortpixel_backup_folder", $backup_folder, $main_file_path, $sizes);

justo antes de devolver la carpeta de copias de seguridad de ShortPixel, normalmente «/wp-content/uploads/ShortpixelBackups». El código $sizes son los tamaños del array de los metadatos;

For version 5.0.0 and later:

$directory = apply_filters("shortpixel/file/backup_folder", $directory, $file);

just before returning the ShortPixel backup folder, usually /wp-content/uploads/ShortpixelBackups).

apply_filters('shortpixel_image_exists', file_exists($path), $path, $post_id);

el ID de la entrada no siempre se establece, solo si es una imagen de la biblioteca de medios;

apply_filters('shortpixel_image_urls', $URLs, $post_id);

filtra las URL que se enviarán a optimizar, $URLs es un arreglo simple;

The filter below is deprecated starting with version 5.0.0!

apply_filters('shortpixel/db/chunk_size', $chunk);

the $chunk is the value ShortPixel chooses to use as the number of selected records in one query (based on total table size), some hosts work better with a different value;

For version 4.22.10 and earlier:

apply_filters('shortpixel/backup/paths', $PATHs, $mainPath);

filtra el array de rutas de las imágenes enviadas a copias de seguridad, y se puede usar para excluir ciertas rutas/imágenes/miniaturas de las copia de seguridad, según la ruta de la imagen. $mainPath es la ruta de la imagen principal, mientras que $PATHs es un array con los archivos a copiar (incluidas las miniaturas);

For version 5.0.0 and later:

apply_filters('shortpixel/image/skip_backup', false, $this->getFullPath(), $this->is_main_file)

filters the images that are skipped or not from the backup. Return true for the type of images to be skipped in the backup. If you check if is_main_file is true and return false (do not skip backup), while while otherwise returning true, the backup will be kept only for the main image. We suggest using it in conjuction with this action that fires right after the restore from backup is done:

do_action('shortpixel/image/after_restore', $this, $this->id, $cleanRestore);

This action can be used to cleanup the meta data from the database, regenerate thumbnails after restoring the main file, writing the updated meta data, etc.

apply_filters('shortpixel/settings/image_sizes', $sizes);

filters the array ($sizes) of image sizes that can be excluded from processing (displayed in the plugin Advanced settings);

apply_filters('shortpixel/image/imageparamlist', $result, $this->id, $this);

filters the list of parameters sent to the API so that resizing can be performed more granularly;

apply_filters('shortpixel/api/request', $requestParameters, $item_id);

filters the parameters sent to the optimization API (through $requestParameters), described in detail here: ShortPixel Reducer API; $item_id contains the ID of the Media Library item, or the ID of the Custom Media item (when used). In short, this filter can be used to alter any parameters sent to the API, depending on the needs. For example, you can set different resize parameters for different post types, different compression levels, remove EXIF or not, covert WebP/AVIF, and basically any other parameter that is sent to the API for a specific image (together with all its thumbnails).

This filter enables the background ShortPixel processing in additional pages (see here the original list). Here’s an example of this filter that enables the processing on the Comments screen (to be placed in your functions.php file):

add_filter('shortpixel/init/optimize_on_screens', function ($screens) {
    $screens[] = 'edit-comments';
    return $screens;
});

The edit-comments is the ID of the screen where you want to enable the processing.

If you want to add multiple pages, here’s what the snippet looks like:

add_filter('shortpixel/init/optimize_on_screens', function ($screens) {
    $screens = array('edit-comments', 'plugins', 'another-custom-post-type-page');
    return $screens;
    });


add_filter('shortpixel/image/filecheck', function () { return true; });

This filter forces a file check for WebP/AVIF in case they were manually removed from disk.

If you want to disable the automatic cache flush that is triggered after image optimization, you can use this filter:

add_filter( 'shortpixel/external/flush_cache', function() { return false; } );

Para definir miniaturas personalizadas para que se procesen en la optimización, tienes dos opciones, donde ambos defines tienen separaciones por comas:

define('SHORTPIXEL_CUSTOM_THUMB_SUFFIXES', '_tl,_tr');

gestionará miniaturas personalizadas como «imagen-100x100_tl.jpg»;

define('SHORTPIXEL_CUSTOM_THUMB_INFIXES', '-uae');

gestionará miniaturas personalizadas como «imagen-uae-100×100.jpg»;

define('SHORTPIXEL_USE_DOUBLE_WEBP_EXTENSION', true);
define('SHORTPIXEL_USE_DOUBLE_AVIF_EXTENSION', true);

will tell the plugin to create double extensions for the WebP/AVIF image counterparts, for example, image.jpg.webp/image.jpg.avif for image.jpg;

Enable the «Trusted mode» in case the file system has limitations and is very slow in responding to direct file operations by adding this constant:

define('SHORTPIXEL_TRUSTED_MODE', true);

This will simply skip file check operations and if the Media Library loads very slowly or freezes, you might want to try adding the constant above to your wp-config.php file.

Disable the feedback survey when the plugin is deactivated:

define('SHORTPIXEL_SKIP_FEEDBACK', true);

Oculta los ajustes de Cloudflare definiendo estas constantes en el archivo «wp-config.php»:

define('SHORTPIXEL_CFTOKEN', 'the Cloudflare API token that has Purge Cache right');
define('SHORTPIXEL_CFZONE', 'The Zone ID from the domain settings in Cloudflare');

Add HTTP basic authentication credentials by defining these constants in wp-config.php

define('SHORTPIXEL_HTTP_AUTH_USER', 'user');
define('SHORTPIXEL_HTTP_AUTH_PASSWORD', 'pass');

Preguntas frecuentes

¿Cómo es ShortPixel comparado con otros plugins de optimización de imágenes (por ejemplo, Smush, Imagify, TinyPNG, Kraken, EWWW), Optimole?

ShortPixel tiene constantemente mejores tasas de compresión junto con más funciones, soporte de copias de seguridad y tiene planes mensuales o de un solo uso muy asequibles.
Estas son un par de reseñas independientes:
AuthorityHacker – «ShortPixel es nuestra herramienta preferida, simplemente porque está bastante automatizada – básicamente dejamos que haga lo suyo.» (lee la reseña completa)
WP Modula – «Una de las razones por las que personalmente soy un gran admirador de ShortPixel es el soporte integrado para formatos de imagen de nueva generación como WebP.» (lee la reseña completa)

¿Puedo usar la misma clave de API en múltiples sitios?

Sí, puedes hacerlo.
Mientras tengas créditos disponibles, ¡puedes usar una única clave de API en tantas webs como desees!

¿Qué plan es el que más me conviene? ¿Qué me recomendáis?

Cada uno tenemos necesidades diferentes, pero en general, recomendamos comprar un plan de créditos de un solo uso para optimizar toda tu biblioteca de medios y luego coger un plan mensual para optimizar tus subidas futuras. Para saber más, dale un vistazo a esta comparativa

No sé cuántas miniaturas tengo, ¿qué plan debo coger?

Para saber cuantas miniaturas tienes, simplemente instala el plugin y ve a Medios > ShortPixel en lotes. El plugin te dirá cuántas miniaturas tienes. Según The plugin will tell you how many thumbnails you’ve got. Basado en esto, dale un vistazo a nuestros planes

¿Puedo mejorar o reducir fácilmente mi plan?

Por supuesto. Puedes actualizar o reducir tus planes con un par de clics desde tu cuenta en shortpixel.com.

¿Puedo probar/usar el plugin gratis?

Sí, puedes hacerlo.
Ofrecemos 100 créditos gratuitos de optimización de imágenes cada mes. Superar la cuota mensual gratuita pausará el proceso de optimización hasta que la cuota se restablezca o amplíe comprando uno de nuestros planes.

¿Puedo optimizar imágenes que no existen en la biblioteca de medios?

Por supuesto.
De hecho, puedes optimizar cualquier imagen que tengas en tu sitio, independientemente de su ubicación. Solo tienes que añadir, en la sección Avanzado de los Ajustes de ShortPixel, las carpetas donde se ubican las imágenes que quieras optimizar y ShortPixel hará su magia y hará el resto.

¿Puedo optimizar imágenes antiguas y nuevas?

¡Por supuesto!
Puedes optimizar todas tus imágenes y fotos, antiguas y actuales, usando nuestra página de «ShortPixel en lotes» en tus medios con un solo clic.

¿Un crédito = una imagen optimizada?

Yes, that is correct.
But please note that usually, an image in Media Library has 5 or more associated thumbs. Each optimized thumbnail requires a credit. In the rare cases when ShortPixel does not optimise the image (lossy) with at least 5%, the credit will not be consumed, though.

¿Puedo restaurar mis imágenes? ¿Qué pasa con las originales?

If you choose the «Image backup» option in Settings/ShortPixel then the original version of any optimized image or PDF will be saved in the backup folder.
The original image is needed if you want to restore an image or if you want to convert an image from lossy/glossy to lossless or vice-versa.

¿Qué tipos de formato se pueden optimizar?

ShortPixel optimises JPEG (JPG, JPEG, JPEG 2000, JPEG XR), PNG, GIF (animated and still), and PDF type of files.

¿Tenéis planes de un solo uso?

Sí, tenemos.
Los créditos que vienen con nuestros planes de un solo uso nunca caducan. ¡Bien! 🙂

¿Qué pasa con mis imágenes existentes?

Tus imágenes existentes son reemplazadas por las optimizadas.
Si eliges la opción de copia de seguridad, las originales se guardarán en una carpeta separada para que puedas restaurarlas si alguna vez necesitas/quieres hacerlo.

¿Cómo funciona el plugin?

Our lightweight plugin sends the original images to our Image Optimization Cloud where they are compressed. ShortPixel then downloads the optimized images and the unoptimized originals are replaced with the optimised versions.

¿Optimizáis las imágenes en la nube?

Yes, all the images processed by ShortPixel are optimized in the Cloud. This takes the load off of your server and allows us to produce the best results.

¿Qué métodos de pago son aceptados?

We accept payments via card (Mastercard, Visa, Maestro, American Express, Discover, Diners Club, JCB, UnionPay), PayPal, and Apple Pay.

¿Cómo activo la clave de API en un multisitio?

Tienes que activar el plugin en la administración de la red y, después, activarlo manualmente en cada sitio individual del multisitio. Una vez que lo hayas hecho, aparecerá el menú de ajustes y podrás añadir la clave de la API para cada sitio individual.
Como alternativa, puedes editar el archivo «wp-config.php» y añadir esta línea:

define('SHORTPIXEL_API_KEY', 'APIKEY');

donde APIKEY es la clave recibida de la API al registrarse.
Si se configura de esa forma, la clave de la API se usará para todos los sitios del multisitio, pero solo será visible en la página de ajustes del sitio principal, estando oculta para el resto de los sitios.

I am not the only one working on the WordPress Dashboard. How can I hide my API key?

Hay una sencilla forma de ocultar la clave de la API, todo lo que tienes que hacer es añadir estas dos líneas a tu archivo «wp-config.php»:

define('SHORTPIXEL_API_KEY', '<<your api key here>>');
define('SHORTPIXEL_HIDE_API_KEY', true);

¿Cuánto es un crédito?

Se utiliza un crédito cada vez que ShortPixel optimiza una imagen o miniatura en al menos un 5%. Si no podemos optimizar una imagen o miniatura en al menos un 5%, no se utilizará ningún crédito 🙂
Ten en cuenta que, por lo general, las imágenes en tu biblioteca de medios tienen 3-5 miniaturas asociadas, y se utilizará un crédito por cada imagen destacada o miniatura asociada que se optimice.

Why shall I use a WordPress plugin and not an offline tool?

Because ShortPixel algorithms were perfected while optimizing over 3.5 billion real-life images.
ShortPixel not only offers the best compression for JPEG, PNG, GIF, and PDF files but it also saves you a lot of time. You just install it on your site and then ShortPixel will take care that all the images on your site are immediately optimized after upload.

¿La optimización de imágenes afecta a mis etiquetas ALT?

No, ShortPixel solo optimiza las imágenes, no tocará nada más como tu HTML/CSS.

Si dejo de usar ShortPixel, ¿mis imágenes permanecerán optimizadas?

¡Por supuesto!
Una vez optimizadas, las imágenes permanecerán optimizadas a menos que elijas explícitamente restaurarlas. ¿Pero por qué hacer eso? 🙂

¿Tengo que pagar mensualmente o una vez?

We have both options available.
One-time credits never expire and are a bit more expensive. Check out our prices here

¿Cuándo puedo cancelar un plan mensual?

Cuando quieras.
Los créditos que aún tengas disponibles en el período de facturación actual seguirán estando disponibles hasta el final del período de facturación. Al final, no se te volverá a facturar y el plan se restablecerá al plan gratuito.

When do credits expire?

Los créditos mensuales caducan después de 30 días, mientras que los créditos de un solo uso nunca caducan.

¿Tenéis una API?

Sí, tenemos varias APIs y herramientas.
Puedes obtener más información acerca de esto aquí:
https://shortpixel.com/api-tools

Can I use the ShortPixel WP plugin on a localhost installation?

Lamentablemente no 🙁
Pero puedes utilizar nuestra herramienta de línea de comandos o nuestra herramienta web
https://shortpixel.com/web-tool-docs
https://shortpixel.com/cli-docs

¿Cómo funciona el redimensionamiento?

Si eliges la opción para cambiar el tamaño de las imágenes de tu sitio, entonces la imagen destacada puede ser redimensionada a un tamaño predefinido, manteniendo su aspecto y sus proporciones intactas. Las miniaturas asociadas no serán redimensionadas.
Con esta opción puedes subir de forma segura las imágenes originales sin necesidad de procesarlas previamente para hacerlas más pequeñas.

¿Funcionará ShortPixel si mi web usa CloudFlare?

¡Por supuesto! A veces tendrás que asegurarte de poner algunas IPs en lista blanca. Simplemente contáctanos y te echaremos una mano.

Where do I report security bugs found in this plugin?

Please report security bugs found in the source code of the ShortPixel Image Optimizer plugin through the Patchstack Vulnerability Disclosure Program. The Patchstack team will assist you with verification, CVE assignment, and notify the developers of this plugin.

I have been using shortpixel for a while with good results but only recently needed to contact customer support. I have been back and forth with quite a complex case that needed investigation. The team has been so patient, explaining everything to me and investigating further, which has taken a few days. They adjusted my settings to get the desired result, and I am very happy with the resolution. Thank you Shortpixel for your great service! 🙂

I love this plugin for compressing my images. You can not only set how high the compression should be, but also whether you want to convert the images into a new format and thus make them even smaller. Simply brilliant!
