Plugin that uses Lokesh Dhakar's Lightbox script as a neater way to enlarge thumbnails (see http://www.huddletogether.com/)

Two versions provided - v1 is less impressive.  Choose one or the other but don't mix

1) Upload the contents of /clientscript into the corresponding forum directory
2) Ditto upload /lightbox-icons into forums/lightbox-icon 
3) Install the lightbox plugin

Effects:

The thumbnail magnifying glass does something quite wonderful.

With version 2, the extra launches a full slide show of all the images in the current category.  Hover
on the overlaid image for 'Previous' and 'Next' buttons.

The displayed image is sized according to the setting *link_imagemagsize* pixels.  If this setting=0, then the
image is shown full size, even if that is bigger than the screen.
