If your talking about your sig, then what you have to do is save the photo you want in a folder. Then go to a hosting website, such as http://www.imageshack.us/, and host your pic by browsing from your folder, and pressing host it! This site will give you a few links, take the hotlink for forums link, and copy it. Click on your control panel at the top, then my signature, and paste this link that you have copied in the space.
