Okay. I get that about cache.
The section here about the shortcode I’m still slightly confused about.
There is no [thumb] shortcode within the [file_list_extended] which is where I need to change the image size.
I’m struggling to understand how I can override the $thumb = wpdm_dynamic_thumb($filepath, array(88,88));
when using the filter you mentioned earlier add_filter('wdm_before_fetch_template','my_fetch_template',10,1);
where we can edit the ‘tag value’ but I’m not certain what this tag value can or needs to be.
