If you upload your photo, then copy the IMG Code for Forums & Message Boards link that it gives you for your photo, you can paste that link directly into the reply box or new thread box anywhere on the forum. Your photo will show in it's actual size and be much easier for everybody to see.
Hope this helps! I've noticed a problem with quite a few photo uploads and now we've got the deer contest going, this should make it a lot easier.
