Click one of the three images to see a larger version.

Explanation
If you often show thumbnails of larger images on your webpages - then this is for you!

It is a small script, that lets you specify the large image to show when the thumbnail is clicked
...then the script opens a new window, loads the image into that window, figures out the size of the image, and resizes the window so it fits!
What more do you want? : )

Go ahead ... try it out, click the kitties!
