I'm looking for some ideas.

My client wants to have the thumbnail images at the top of his site to automatically scroll from left to right or vice versa. And when the user rolls over one of the images he wants it to popup as a larger image.

Are there any add-on blocks that would allow me to do this or does anyone have any good ideas on how to go about creating this feature? I've attached a screen shot of the site so you can see what the thumbnail images look like.

I've downloaded and paid for about three add-ons and looked carefully at all the others, but still can't seem to find anything that will work, but there may be something I am missing. Thus the reason I am trying the forum. Thanks!
