The BLT banner in my signature was set up by another Diser and we were told on a thread we can use it. If that BLT banner is one you would want then follow these directions. Just right click on the banner below in my signature and go to properties, copy the URL in the properties then go to User CP, then edit signature, there is a white box that you can copy the URL into and then preview your signature. I think that is all the steps.
As for others like the one I have with my DD and Mickey in it, I set that one up through **************. Good luck and PM me if you need any other help.
