Must be an editing thing?
None of the pictures are showing up on Myspace if you've edited your profile today. No matter what image hosting site you're using- photobucket, tinypic, etc, it's all the same thing... little boxes with no pictures. If you haven't edited your profile today, then your pictures still work. It must be a Myspace problem, right?
Yes, it is obviously a myspace problem. Someone else suggested this in another question so it is most likely myspace's problem.
