I wanted a module that displayed thumbnails which, when pressed, displayed the full photograph. You can then page through other photos or close the window. This free lightbox does exactly that. I am not very technical but I found it very easy to set up (just tell it where your images are) and I had it working in just a few minutes. There was one slight problem (no one's fault really) but the support team suggested an easy fix and now the product works perfectly. There may well be lots of other features in the lightbox but I have not tried them. What I can say is that if you need a facility to display images nicely then I would recommend this one.
