1) Script Title: Thumbnail Viewer II

2) Script URL (on DD): http://www.dynamicdrive.com/dynamicindex4/thumbnail2.htm

3) Describe problem: I am to add a popup frame on the bottom of the thumbnail that displays when a user mouses over the thumbnail and was wondering if anyone has a sample of this feature. Basically what I want is to display a small area on the bottom of the thumbnail when a user mouses over it.

Below is the script I am currently using with some changes I made to include a background in the popup. The changes I made are in bold and underlined. I am also including an image that represents what I am trying to do with the popup. I have the frame with the image showing just fine but I can't seem to get the small image on the top right corner to appear correctly.

In addition to the above I want to know how I can make the popup close automatically if a user does not take further action like mouseover the popup or click the popup itselt.

I could really use some help here since I'm not that good with javascript or jquerry.
