I've tried adding multiple images manually, and I can't seem to get them to show up no matter what I do. Is there any general thing that can be causing this, like a switch somewhere in the admin forums? I just installed Image Handler 2 as well, and I can see all of the previous images I had manually uploaded, meaning that they are named correctly (_MED, _LRG).
For some reason, they just aren't showing up on my page. Can anyone lend some advice?
