Image Thumbnail Viewer is a
compact, unobtrusive image viewer that can be applied to any link on the
page to load the desired image inside a sleek interface based on the link's "href" value. Simply give the link in question- be it a text
link or image thumbnail link- a rel attribute of "thumbnail",
and you're done.
This script will center the enlarged image on the page and
optionally display a text description based on the activating link's
"title"
attribute. A fading effect can be turned on/off
to bring the final image into view.
