Hey Eric,
For me it was just the way that I was implementing an image viewing Class in my Flash file, it didn't really have anything to do with Myspace (but I thought it did, at first.) If you are properly getting the image URI imported to your Flash file, there should be no reason why your Flash file wouldn't display it. Maybe try displaying the image a different way in your Flash file?
I hope you can get it figured out!
