Fixed Tooltip: Problem with overlay.gif /background not fading

1) Script Title: Fixed Tooltip

2) Script URL (on DD): http://www.dynamicdrive.com/dynamici...xedtooltip.htm

3) Describe problem: Hi, I'm having a problem with the overlay feature on this lightbox. The image is working, but the overlay/background fade isn't - so it isn't getting that faded background effect. Is there something I'm missing? I've changed all the parts I can see to images/overlay.gif instead of overlay.gif...as i change the folder but was there something else I'm supposed to change?
