If you have already checked the one called Browser Like(2) under the same category, you'll find this very similar. Difference being, I've simplified the script and "onmouseover" it opens yet another image.
I have used two event handlers that are supported inversion 4.0 browsers. These are "onMousedown" and "onMouseup". These two in combination "changes" the image(s) so long the mouse key is depressed.
In addition, to ensure you do not have any problem with older browsers - I have allowed access in three steps. It first checks for JavaScript support, then JS1.1 & finally JS1.2. So if the browser is JS1.1 type (e.g.: Netscape 3.0), then, while the"onMouseover" will work, the"Mousedown/up" will be ignored.
As far as the Script is concerned, it's a wee bit more complicated than the Standard ones. The reason being, I wanted to make the "onMouseover" and "onMouseout" event handlers to work with both JavaScript V1.1 as well as JavaScript V1.2. The modified script makes the Functions with names CHANGEON & CHANGEOUT work on all browsers with JavaScript1.1 AND/OR above. But, CHANGEDN & CHANGEUP are ignored by non-javascript1.2 browsers (older than version 4)
PS: It's all yours if you want. As usual, you can break it, twist it, use it or dump it! However, no matter what you eventually do with it, I'll be very happy if you signed my Guestbook in the meantime! Thanks.
