I can't figure out how to do this. Any help?

 

Yeah, I just did it. Took a bit to figure it out.

First, go to your signature link in your control panel and click the box that says "delete current pic."

Then save it.

Then go back to the signature page (it should not have a pic anymore) and upload your new pic.

 

Cool.

 

I figured it out!!!!

Thanks anyway.

 

Hit user cp at top left, hit edit signature, scroll down to picture, browes, upload
