jquery colorbox embedded video links

I have just downloaded and installed the Jquery Colorbox to use with RGG. It works fine for all the images in the gallery I have created but I’m wondering if there’s a way to get one of my image thumbnails to link directly to an embedded vimeo file? I know Colorbox has this capability, I just can’t figure out how to use it with the RGG plugin. Thanks
