Auto-Ads Script / Advertisement Script

I want a script that automatically add banner ads (different sizes compatible/auto-sizes) only on top of <iframe></iframe>, <embed></embed>, <object> and all kind of <embed codes> with alignement: centered on both horizontal and vertical beside the embeded videos. I will use ads service (publisher service) from websites like adbrite etc. The visitor will have to click on ad (banner) to remove it (dissapear), all functions from website will have to not be locked or something. If the ad is with text the visitor will have to click on a link from that ad that will open in a new window and the ad from the main website will dissapear. If the ad is banner with a flash/image all that area will supposed to have a link and the visitor will have to click on it, the ad from the main site will dissapear and the ad will open it's website in a new window. That (i) info below the banner is supposed to be there to inform the visitor what will have to do. The script will had a place where to add the ads code. I hope is enough information. Thanks
