Ok so I've been searching and searching and I still can't figure this out. It's not a super big deal but it's a pain..

When logged into my admin and in the Image Handler section, I can upload images fine but the thumbnails don't show (instead a broken image icon is displayed).

Everything that I can tell works fine on my site otherwise. Images that I upload through IH also get uploaded correctly to my site and display fine on my real site, just not in the admin area. The only other issue I've heard about this in this thread is someone who was having them uploaded to the wrong directory (not even showing on his main site) because of a possible config.php setting but I don't even think I've touched that file, and plus my images are loading fine on my main pages. Installation went through perfect the first time as well and everything seems to function perfect on my store except for this....
