<br><br>zoOom is very easy to customise.
<br>You can change the image, it"s position. You can also set the maximum and minimum allowable widths. You can change the zoom speed.
<br>For customising, make changes in the "configure" section of the script.

In this Script when you move you click on the following image, the image size will decrease
gradually (i.e the image will zoom out) and will finally disappear.
<br><br>The script is very easy to customise. Here the event that calls the function is <font face="courier">onclick</font>. You can change it to
<font face="courier">onmouseover</font>, <font face="courier">onmouseout</font> or <font face="courier">onmousedown</font>.
<br><br>To see the script in action again, refresh this page.
