Function item_image_gallery seems to have no filter applied

[DBinaghi]

It looks like the item_image_gallery function has not filter applied, although there's plenty of filters associated to files and their markup.

I wonder whether replacing

if ($attrs['linkWrapper'] !== null) {
    $html .= '</div>';
}

with

if ($attrs['linkWrapper'] !== null) {
   $html .= '</div>';
}
		
$html = apply_filters(
     'file_markup',
     $html,
     array(
          'file' => $file
     )
 );

could solve the issue. Not sure whether any other parameter has to be passed, though.

You definitely don't want to apply the file_markup filter here, it's for a different use so the filters are going to be doing different things and expecting different arguments, and so on.

I would think we could probably most usefully filter on the attributes for each link... we could also/alternatively filter the markup for each link, or just filter the entire markup (usually that's a little unwieldy but sometimes useful). In any of these cases they'd be new filters with new names.

I guess filtering the entire markup would give the most freedom, in this case.
