Move your mouse over a JavaScript link to see the image of your choice plus corresponding description on the pop up, by using this image HTML tooltip script. Each tooltip can have a different background color, just for aesthetics or in case the pictures are transparent GIFs.This code detects for window edges and keeps the tooltip description position inside. The tooltip moving with the mousemove is an option that can be turned off by setting the tipFollowMouse to false.
