i would like to make it on a website that when you hover over a picture/link that it turns the picture/link into the "stamp" filter in photoshop...any ideas?

.... You'd need two images. To make rollovers. Time counsuming, but really the only way to do so.

anyone you recommend choosing in google?

No, I don't know you. CSS rollovers are easier for me, javascript might be easier for you. I personally find this site easy to understand but you might not. That's why I gave you the google link.
