Description

The “ims_allowed_extensions” filter is used to add or remove allowed image file extensions.

A plugin (or theme) can modify the array with the code:

<?php add_filter( 'ims_allowed_extensions', 'filter_function_name' ); ?>

The hook is located in the image-store/_inc/galleries.php file.

Example

// Apply filter
function add_ims_extensions( $extensions ) {
$extensions[] = 'psd'; // add new extension
return $extensions; 
}
add_filter('ims_allowed_extensions', 'add_ims_extensions');

Note: $extensions is an numeric array including file extensions.
