onMouseOver?

Hopefully someone can help me out with this and point me to the summary in the Help file.

In my application, I have a number of images as links. I would like to make it so that when the user hovers over the image, a description appears in a field (not as a tooltip). When they click on it, I want the link to function.

Failing that, is there a way to make the description appear on one click and the link function on the double click?

I am not the best at JavaScript so another way to do it using @Formula or LotusScript is nice.

This is in Notes Client, not for web.

There is no onMouseOver event for the Notes Client. As far as I know, tooltips are as close as you can get to doing this.
