Hello there Stackoverflow.
I have a little job for my website i can't figure out on my own. 

I have a box on the right, where i want all my sponsors, but instead of making the box really long, i just want a simple "slideshow" where it just fades into a picture, it stays for 3 seconds, and it fades into another picture. They're gonna be 90x90 most of them, however some may be different sizes and that shouldn't screw up. 

I have a picture demonstrating, if you didn't get the concept from my poor english.

1=The sponsor picture. At this box it should slide between the different sponsors.

thanks in advance!
