Ok... I'm going to give this a shot here. My real knowledge of html programming is about on par with my speed typing ability. (yup! pretty poor) So forgive me if I just totally messed up you signature as I didn't save the original text before I started editing!
(I had to dig out my Tech Stuff for Dummies book, but I think that's what you're looking for.)
*edit* There were a couple of codes repeated at the end of both of your images making the big spaces, as well as a missing "end code" on the last one that didn't allow your last image to display. *end edit*
BTW... I was referring to myself on the Tech Stuff For Dummies Book... if you saw the jumbled mess I made of your signature earlier you know what I mean!
