Oh! Ok, so what you wanna do is click on the "Pittoo" hidden content, and there should be the skin there. You can either right click on the skin file and save it, or, depending on your computer (I use a mac, so I don't really know much about windows if you're using one) you can just drag and drop the picture to your desktop. If your friend still can't figure that out, you could maybe send it to them if possible? If you need more explanation I'll be happy to help.
