I am trying to use the following script for something.
http://www.dynamicdrive.com/dynamici...thumbnail2.htm

What I have done with this script is that I have a few "loadareas" where the images show up.
So basically I have 3 load areas. "loadarea1", "loadarea2" and "loadarea3". In each load area the default image is a blank gif. But when u click on specific links it changes those blank gifs into another image. For example I have a link "Picture 2" and when I click on it the blank gif in "loadarea2" changes to a specific picture (pic2.gif)

Now the problem I have is that when the user clicks on the above link and the pic changes I need to have the other "loadareas" change back to the blank gif's. So if "loadarea1" had been changed into another picture I now need it to change back to a blank gif when the user clicks on the link for "loadarea2". I hope this makes sense?

Please look at the link to understand how this script works.

If there is a different way of achieving this I would be so grateful for help or tips. Thanks so much.

Just load the blank .gif file the same way you loaded the image. Since it was already downloaded when the page opened, it won't have to be downloaded again.
