Once you've uploaded your sig, find the graphic representation of that file in your account images.Originally Posted by blackhole john
Under that image will be a line of text marked "IMG".
highlight that box, hit Ctrl+C (to copy that text)
Then you can paste that text into your Profile under your custom signature setting.
Be aware though, Photobucket is not as reliable as Imageshack or some of the others as keeping your image "viewable".
Once in awhile their servers get nutty and you won't see your image in your sig. (Just a heads up.)
