Creating banner from X-cart products
 

I would like to randomly show products from a category as banner ads on other section of site (not x-cart) or external site. Has anyone done that or suggestion how to do that?
SHould be able to invoke either as javascript or iframe.

I already have hundreds of images (and linked products) in x-cart database. It doesn't make sense to duplicate that to create hundreds of banners.

And ideally I would be able to pass the keywords to retrive products matching that keyword (but perhaps I am asking too much at this stage :) )
