The OnMouseOver scriplet lets you create a link with two images that change when the mouse passes over them.
You need two interchangable images and a html page that you wish to link to.
Press the "Framework" button to get the framework of the scriplet. Enter
your image details and link details, and remember to update the picture number for each additional picture/link you have.
The framework of the scriptlets will tell you where you must place the picture and link tags.
