Here's a little bug with uploading images to ServImg that took me quite a while to figure out. I was doing the same upload process like I've done many times before but the photo would not upload. The problem would occur right after I'd browsed to the file on my hard drive. Turns out ServImg can't find a file if it's buried too deep, in too many subfolders on your drive. My guess is the path has more characters than they alotted space for. After moving the files up "higher" they uploaded fine.
