Go to My Account in the top left, then click the tab labeled "Profile". From there you can select "Edit Signature".
To add a picture, find one that is free for you to use, and copy the url. (Either by right-clicking and selecting "Copy URL address", "Copy Image", "Copy", or by opening it in a new tab and copying the URL at the top of the page) Then post it between image tags:
[img]URL[/img]
And you are not allowed to give out any personal information by the way.
