Ok, I received the image and also couldn't get it to load.
Bad news: I thought it was due to the comma in the filename, but it wasn't that. The only other thing I could think was the filesize was pretty big. I resized it and it uploaded fine... but that could have also rejiggered the filetype problem too.
Good news: We're working on a new system that I've tested with your photo and it uploaded fine.
So, until we have the new system in place, please try resizing the image on your computer and upload or upload to a service like photobucker, etc.
