The myspace backgrounds didn't work for me. I googled "animated yorkies" and when I found what I wanted, I right clicked and saved as and saved the image to my pictures. Then I created an album in my profile and uploaded the graphics to it. When I opened the pic from the album in my profile, just below the pic was the code for it and I just copy and pasted it into the spot that says background. Then I saved the changes.
Good Luck and let me know if you need help.
