Description
By default, GP Media Library will use the default image sizes generated by WordPress (thumbnail, medium, medium_large, large). In addition to these four sizes, the first images registered with add_image_size will also be included.
This filter allows you to modify which sizes are generated for the Image Merge Tags and, if desired, include all of your image sizes.
Usage
add_filter( 'gpml_merge_tag_image_sizes', 'my_custom_function' );Examples
Return All Sizes
If you would like to return all available image sizes, simply return the get_intermediate_image_sizes function in the filter.
add_filter( 'gpml_merge_tag_image_sizes', function( $sizes ) {
return get_intermediate_image_sizes();
}Add A Custom Size
Looking to replace the default sizes and include only sizes that you specify? Simply return an array of image sizes like so:
add_filter( 'gpml_merge_tag_image_sizes', function( $sizes ) {
return array( 'image_one', 'image_two' );
}Add A Size to the List
Need to add an image size to the list of sizes? Simply add the image size to the array of images sizes like this
add_filter( 'gpml_merge_tag_image_sizes', function( $sizes ) {
$sizes[] = 'image_one';
}Source Code
