LAST EDITED ON 03-10-07 AT 08:49 PM (EST)Usually what I do once I have it the way I want is copy the URL of the picture I want and then paste it into the place in the profile for the signature (so I only have to get it in right one time).
I have a file on my puter with all my sigs and I rotate in which ones I'm in the mood for (some are for holiday seasons).
But as long as you copy the right URL it should work.
The Preview button is good for making sure I got it right, so that way it doesn't go live until I know it works.
