Size medium_large not managed

Hello,
I just noticed that the medium_large WordPress size seems not be registered globally. It seems this size is generated automatically when needed.
As a result, it can be found in the attachement’s sizes array, but WPPP do not recognize this size (it’s not set in its specific option containing WPPP known sizes).
So I had to modify function serve_image so that in the try statement, if WPPP do not find a valide size, a secpnd chance it taken as follow:

// 2ND CHANCE START - Try to get attachement's specific sizes
if ( $the_size === '' ) {
	$size_pattern = '/-[0-9]+x[0-9]+\.(jpe?g|png|gif)/';
	$repl_pattern = '.$1';
	$request_uri = $_SERVER['HTTPS'] ? 'https://' : 'https://';
	$request_uri .= $_SERVER['SERVER_NAME'];
	$request_uri .= preg_replace ($size_pattern, $repl_pattern, $request);
	$postid = attachment_url_to_postid($request_uri);
	if ( $postid > 0 ) {
		$meta_d = wp_get_attachment_metadata($postid);
		$sizes = $meta_d['sizes'];
		foreach ( $sizes as $size => $size_data ) {
			// always check, even if size is in meta data, as the size could have changed since it was saved to meta data
			$new_size = image_resize_dimensions( $imgsize[ 'width' ], $imgsize[ 'height' ], $size_data[ 'width' ], $size_data[ 'height' ], $size_data[ 'crop' ] );
			if ( ( abs( $new_size[ 4 ] - $this->width ) <= 1 ) && ( abs( $new_size[ 5 ] - $this->height ) <= 1 ) ) {
				// allow size to vary by one pixel to catch rounding differences in size calculation 
				$the_size = $size;
				$crop = $size_data[ 'crop' ];
				break;
			}
		}
	}
}
// 2ND CHANCE END

I know it may not be the proper solution, but this kludge manages the 768x… medium_large size some images have.

I’m sure you’ll find a better way to do that.
Just to share and help your plugin improve. ??

Thank you
