Set website as homepage:

This set as homepage script gives your visitor the option to set your site as their browsers homepage. I found this script online with no credit intact

If you want to trigger the script automaticlly put

onLoad="makehome()" 
 

in your body tag. To trigger the script by clicking a link put

onClick="makehome()"  

in your image or link tag.

Example:

<img src="../../path/to_image/img.gif" onClick="makehome()">
