It did help thank you very much,

On the fourms, there is a bar near the top of the page that says FAQ, search, members etc.
Go to where it says User Control Panel and when you get there, look for the word 'options.' It's near the left of the page. Scroll down to "profile" and then go to the options list again. Under profile, there is signature (the bottom image you talked about) , avatar, and other account settings like your age, where you live, stuff about you. Well that's it! Hope this helped!
