Thank you, after a few modifications I got it working as I want it to.

Ok after I found where I should put this script and it works, its didn't close Adobe reader as you said but it works. Thanks for your help

Niall, I have created a document using this method. I have created the drop down list and properly generated the binding values. I have inserted all of the images and checked the imbed image box and set them to hidden. I have created a Javascript according to the one listed above and have tested it with 3 or 4 items and images and it works fine. When I increase the number of items inthe drop down and increase the number of images to about 27 items and save the file, the drop down no longer works...
