Need someone to edit a wordpress lightbox plugin for ads

I need the successful bidder to go into a lightbox plugin that I have and insert code to allow ads (adsense or adbrite) to display when the lightbox opens up underneath or above the image. I just need a quick run through on which files to modify and what needs to be done when I want to insert the code under the image in the lightbox. For an example go to [login to view URL] and click the image now when this opens I require an image/text/ad to be placed either on-top or below this image. This will be a very simple straight forward job for someone who understands the workings of wordpress plugins.
