Re: Not valid image
Same thing here! I tried resizing, different file types, everything. The files are well within the guidelines, but just won't upload. I even tried uploading pics that were already on there (so I knew they'd worked before) and they won't work now. They wouldn't work as attachments either, so it's not just the uploader app. I ended up just posting a photobucket link, but that's not as nice for folks looking. I have a mac, so don't know if that's part of the problem.
