Large images can't scroll sideways with any of the jQuery plugins

I'm running SIGE on my Joomla 2.5 web site. We have large images we'd like to show the visitors but they can't scroll sideways to see the edges of the images. I'd like to use the colorbox jQuery inside SIGE, but I'm not real sure how to add it in. Colorbox (part of Simple Image Gallery Pro) does just what I want, but I love the functionality of SIGE and would prefer to use it.
