d13gallery help

Hey guys, d13gallery is a great plug-in that allows you to make thumbnails in your posts. Is there a way to edit the settings so you can make d13 grab the images from ANOTHER site (it’s mine, I just need the images to be hosted there) instead of from the same site? For instance, if you wanted to make thumbs that links to the original images with d13gallery, all you’d do is point it to where the original images are, usually in the same folder as the site i.e.

<gallery>subdirector/image-folder</gallery>

But what if I have images on ANOTHER site? How do I edit the settings, or the php files, to make it fetch images from THAT site?

Any help would be appreciated.
