Make sure you are saving it as a JPG, and not just calling it that. You should edit the images before hand anyway, like rotating your avatar. Sometimes the files flub, it could be that you are doing it all on a phone. I think apple phones sometimes have issues. Sometimes just doing a SAVE AS and copying over the file makes it work.
Be sure to have more keywords - and you can't sell the harley, they are very hyper about that stuff being sold anywhere.
