add product details button

Hello,
i am stuck with a simple yet annoying problem, how can i change the following button: "Go To This Product's Detailed Information" to simply say "product details", i tried looking for the image to change but to no luck, i uploaded many times the productdetails.gif, but still i cant seem to override it.
any ideas , i really appreciate it

oops forgot the site: http://www.arivacs.com/catalog/

Well, that's a Template Monster template, so what might work on a regular Zencart site might not on yours, but they seem to have CSS buttons activated, so I'd go to Admin - Tools - Developers Tool Kit and search for that string (Go To This Product's Detailed Information) to see where it's defined.

thanks a lot stevesh, that did it
now i gotta find ways to add the "add to cart" button directly below "product details" in "featured products" at the main page
