What script better fits this?

Hello members of TF.
I'm posting this in request to find the best fitting program for my needs.
I've been searching on google, on hostcripts.com and many other random php script resource sites but couldn't find anything usefull enough for me.

I'm running a descent portfolio site and decided to implement a 468x60 ads system but can't find the right program. I just need a script that will let me upload (and/or link directly) an image that will be used with other's to rotate at random.

I have found programs similar to this but most of the once I install come out either something really too complex or very featureless.

Thanks in advance, all the help greatly appreciated.
