Hello! To put it in your sig, right click the user bar and click on "Copy image URL". Then, when you are editing your sig, there is a thing at the top that gives you the option to put a picture in through it's URL. It should be a little picture of a tree and when you scroll over it, it should say "Insert Image". Paste it into the little window that pops up and click "OK". Then, you should be done. If you have any other questions, you can ask me!
