Hope I'm in the correct place...

I want to add Facebook's "open graph tags" to a specific product page in my Zen Cart:

http://www.guitarprinciples.com/shop...&products_id=1

The code for these tags needs to go between the <head> tags, but obviously only for this specific page.

I've found other info on this topic, but in all honesty I'm lost. Can anyone explain to me how to accomplish this?

Thanks in advance!
