Using stylesheet switcher from FSMenu example for images

Could the stylesheet switcher from the FSMenu example page be modified to switch different images? I'd like to use it to allow users on my site to change the logo. (http://master-of-metal.blogspot.com is my site) I don't know if this will work, or if I'll just have to attempt making a new script from scratch, but hopefully there's an easier way, since I don't know scripting at all, and I'm not really familiar with anything but the basic stuff in HTML.

There's a regular image switcher? Oh yeah. . .that does sound kinda familiar. . .DUH! Sorry, I completely forgot about it. Man, I feel retarded, lol. I do have one other question, though. Can the images have rollovers? I've got one right now on my site, but when I put the other images on it, I'd like to be able to keep the rollover and also have rollovers for the other images, if possible.

I've got an image rollover right now, but I don't know how I'd be able to keep it along with the image switcher. How would you be able to make the rollover script know which rollover to use? If I had images A and C, with rollovers B and D, how would I get the script to know that A and B go together and C and D go together? You know what I mean? I guess it could be done with an If statement or something conditional like that, but I'm not sure what the condition would be.

I  just need to learn Javascript. I've wanted to for some time now, but never have really pursued it. I need to go ahead and try it so I can quit bugging you, lol.
