原文外掛簡介
Presswell Art Direction gives editors and developers a consistent way to manage image sizing and cropping in WordPress. Define custom sizes, set focal points, and generate non-core thumbnails only when they are actually needed.
Features
Control image cropping with focal points
Define custom image sizes and nested thumbnail variants
Select custom image sizes directly in the WordPress editor
Dynamically generate non-core thumbnails on demand
Run batch regeneration from a dedicated Media tool
Use Endpoint Mode when filename-based 404 handoff is unavailable
Import/export size definitions and migrate legacy focal-point metadata
Focal Point Cropping
Set a focal point for Media Library images to control how custom crops are framed. Mark the visual subject once, and generated thumbnails stay centered on the correct area.
Custom Size Management
Use the settings UI to define and edit custom image sizes. Registered sizes become available when inserting images in the block editor and classic editor workflows.
Dynamic Generation + Endpoint Mode
Presswell Art Direction avoids generating every custom size at upload time. WordPress core sizes are generated normally, while custom sizes are generated when requested in templates or by URL.
If filename-based 404 image requests do not reach WordPress (common in some NGINX/server setups), enable Endpoint Mode (/pwad-image/?id=...&size=...). The plugin includes an automatic compatibility check in wp-admin.
Regenerator
The Regenerator screen (Media -> Regenerate Thumbnails) builds a queue and processes images in batches, with progress metrics and retry handling for failed jobs. You can choose exactly which sizes should be regenerated.

Public APIs
pwad_add_image_size( $args )
$args (array) (required) – Keyed array containing name, key, height, width, crop (optional), and optionally thumbnails values.
Thumbnail keys are prefixed with parent’s key like [size]-[thumbnail].
Example:
pwad_add_image_size( array(
'name' => 'Square',
'key' => 'square',
'width' => '1200',
'height' => '1200',
'crop' => true,
'thumbnails' => array(
array(
'name' => 'Medium',
'key' => 'medium',
'width' => '800',
'height' => '800',
),
array(
'name' => 'Small',
'key' => 'small',
'width' => '400',
'height' => '400',
),
),
) );
pwad_get_image_sizes()
Returns all currently-available sizes (WordPress defaults + plugin/theme sizes + Presswell Art Direction sizes/thumbnails).
Example:
$sizes = pwad_get_image_sizes();
pwad_get_image( $attachment_ID, $size_key, $attr = array() )
$attachment_ID (int) (required) – ID of image attachment
$size_key (string) (required) – Image size identifier (thumbnail, large, my-size, my-size-mobile, etc.)
$attr (array) (optional) – HTML attributes passed to the rendered image element
Returns an image tag.
Example:
$square_large = pwad_get_image( $img_ID, ‘square’ );
$square_small = pwad_get_image( $img_ID, ‘square-small’, array( ‘class’ => ‘hero-image’ ) );
pwad_get_image_src( $attachment_ID, $size_key )
$attachment_ID (int) (required) – ID of image attachment
$size_key (string) (required) – Image size identifier (thumbnail, large, my-size, my-size-mobile, etc.)
Returns a keyed array containing the file, url, path, height, width, and mime-type values.
Example:
$square_large = pwad_get_image_src( $img_ID, ‘square’ );
$square_small = pwad_get_image_src( $img_ID, ‘square-small’ );
Actions
pwad/image_generated
Fires immediately after a custom crop file is generated so themes/plugins can queue optimizers or post-processing.
Arguments:
$data[‘attachment_id’] (int) – Attachment ID.
$data[‘size_key’] (string) – Requested size key.
$data[‘size_data’] (array) – Registered/requested size definition used for generation.
$data[‘source_file’] (string) – Source file path from attachment metadata (relative upload path).
$data[‘generated_file’] (string) – Generated filename for the new crop.
Example:
add_action( ‘pwad/image_generated’, function( $data ) {
// Example: queue optimization when a new crop is created.
if ( ! empty( $data[‘attachment_id’] ) && ! empty( $data[‘generated_file’] ) ) {
do_action( ‘my_optimizer/queue’, $data );
}
} );
