Images in Signature

I feel like there's a really easy answer to this, but I don't know what it is, so...

When I try to put images of all my covers in my signature, I get a message saying that there's too many characters, or whatever. I assume that's because each image comes with a whole long link code referring back to my photobucket account. (I know, my terminology is off... hopefully it's understandable) Given that, I haven't even tried to add links to make the images clickable.

So, assuming that I'm abandoning the 'each cover has a link to its page on my website' plan, I'm thinking that I could just have one photobucket image that is all of my covers stretched out next to each other. But I can't figure out how to make that image. I usually use Gimp for the limited photo manipulation that I do, but when I try to add more than one cover, they stack on top of each other instead of lining up side to side.

Like I said, I'm pretty sure there's an easy solution to this, but I have no idea what it is...

Thanks for any help.

Huh. So is there another way to do this?

I see people with a whole string of images along the bottom... well, I've seen seven, at least, and I think more.

It's not a tragedy if I can't fit them all, I just don't like having to chose which ones to include!

Woo Hoo, I made it work! Yay!

Thanks, guys.

(Now, does it look too big? Like, is it gaudy instead of celebratory? Damn...)
