Not sure if title makes sense but I was wondering if there was anyway I could specify a thumbnail image which is different to the image that opens up?

 

Thanks in advance for any ideas

yes, have a look at, for example, Lightbox 2

 

http://lokeshdhakar.com/projects/lightbox2/#how

 

 

<a href="images/image-3.jpg" rel="lightbox[plants]" title="Roll over and click right side of image to move forward."><img src="images/thumb-3.jpg" width="100" height="40" alt="Plants: image 1 0f 4 thumb" /></a>

 

The href is what gets lightboxed, the img src is the link.

Arh that's great, exactly what I'm after...thanks you!
