Need Script to Dynamically Display Images On Webpage

Need a script that will pull images on my server on to my webpage dynamically based on the keywords I'm bidding on in google adwords Example: I bid on the keyword "Heroes", I would then need my webpage to dynamically insert the "Heroes" banner image (already on my server) into my webpage at a certain location. That's essentially it, I can provide more details once this project is awarded. Please only bidders/programmers from USA, Canada, Australia or UK with very good english skills
