Very quickly: I had a message this morning that images were not displaying properly - for some reason the were appearing behind the template. I tested it in Firefox, and it seemed fine. Tested in Chrome and Internet Explorer, and lo-and-behold, images clicked on displayed behind everything...
I'm not entirely sure why it was happening, but it was something to do with the "Lightbox" image display feature. So that is now disabled, and it SHOULD be working properly now.
I will get on to the Template designer and let them know. Thanks Sue for letting me know :)
Fingers crossed it's all fixed now!
