Plugin to show image or image gallery, with full URL below the image

Hi all,

Does anybody know a plugin I could use to automatically upload a gallery to a page and then have each of the images show its full URL below the image?

We run book tours and would like to offer users the ability to hotlink from our server, to save them dealing with the images themselves, as many of them are not tech-savvy, and this would be much easier for them, but I don’t really want to do this by hand as it would take a lot of time.

Thanks.
