At the top of the page, click "user cp"
then click "edit profile"
then about half way into the page it says "Signature" there you can put whatever you want, but if you want a pic, you have to have pictures some where that will let you crosspost. The only place I know of right now besides your own web page is Imagestation. You have to upload your pictures there.
Then after you upload, rightclick- properties then copy & paste the address here using the ~IMG~ where the vb code is.
