I was just wondering if anyone knew of a way to have a script dynamically change image names or insert words based on an end-user input in to a HTML page?

For example, lets say one of my affiliates on Condom Cash wanted to send their traffic to a site using the keywords 'twink fetish' they could be given a url like this...

domain.com/id=affid&keyword=twink+fetish

Which would basically send them to a generic site but various parts of the tour would have changed (text) to include the words 'twink' and 'fetish'?

Also, im thinking this could work really well when it came to naming tour page images, so does anyone know of such a script or, if it would even be possible to do?

Regards,
