Custom Banner Using Random Images and Graphic Overlay?

[SamirDarji]

I got this idea when I saw the random images at the top of www.dgrin.com and started seeing the dhtml/ajax popups that sites are now using.

Since it is possible to overlay graphics on top graphics with transparency, how hard would it be to overlay a graphic onto a series of images like at the top of www.dgrin.com ? Since you can use some sort of transparancy, you would have a completely dynamic banner that changes constantly.

This is what I'm set out to do, but I have no real experience in coding. I can figure out syntax and methods/functions and how to implement things, but I need almost an exact example for me to be able to reverse-engineer it and then use it for my purposes.

I've built a vbadvanced module which is basically just a table with the images just like www.dgrin.com. Now I need to figure out how to overlay my graphic over the table.

Any assistance or guidance appreciated.
