Excellent solution! The user agent detection works for me, but I had to use:

@Raphael: Since FB reaches out to grab the page, you won’t be able to do it with Javascript. However, you could cause the Like button to feed a variable, like \page.html?id=245\ and have PHP or whatever language your using dynamically create the rel tag based on that.

Is it possible to dynamically change facebook LIKE thumbnail? Basically,
1. I have a script that allows you to scroll through about 30 photos.
2. There is one facebook LIKE button on the page, but the facebook iframe src is dynamically changed to include the photo id of the current photo so that the LIKE is specific to that photo.

All the above work and I’m able to specify a pre-generated thumbnail photo that is displayed on facebook when one clicks the LIKE button.

Is it possible to dynamically modify the [link rel="image_src" href="http://domain.ext/image.png" /] whereby a new thumnail is set for each photo?

@Steve: (a) That would certainly work, but it has two flaws. One, you’re forcing users to download the image, while the link tag doesn’t, and two, you’re not forcing a specific image, but letting users choose what to display. (b) I REALLY wish they documented this, unfortunately I have no idea.
