First of all, thanks a lot for this plugin. : )
So, here's the deal: the plugin works like a charm. I can add thumbs to my categories, list them wherever I want, but there's something weird. After clicking on the Add Thumbnail to Category button, I can't actually see the thumbs on my admin area. I can only see a deleted image icon ( /plugins/taxonomy-images/deleted-image.png ), although everything else keeps working fine.
What could it be?
Thanks a lot!
