Somebody explain to this dumb Polack how to change your sig pic. I find it, upload it, hit save, and I still have the same one. I try something else and it brings up the SIGPIC codes, but then I don't know what to do to maneuver the picture in there. Do I put in the URL from the folder on my computer, from a website, what?

I logged out, cleared cookies, logged back in, old pic is still there.
