I'm having some trouble getting avatars to work on my site. I'm sure I'm just not doing something right. I've downloaded many different avatars and uploaded them to my images folder on my site. How do I get them to show up in the gallery? It shows that I have selected an avatar, but won't load it. I just get the little white box with a red X. I have avatars enabled on my site and their dimensions and file size meet the requirements. Anyone have any ideas?
