I think I would rather be a brain surgeon than try to work out how I managed this BUT if you follow the directions (by the expert, Ilker) below you should get it ......
1.) Copy and paste the matrix of “Viral Icons” below courtesy of Ilker Yoldas from The Thinking Blog.
2.) Upload your non-animated favicon (GIF image of size 16x16 pixels) to ImageShack, a similar free image hosting server or to your own server provided by your hosting service if you have one.
3.) Substitute the Host Icon and one of the “Viral Icons” in the matrix with your ALT text of choice and your blog’s URL. Maximum of 3 specific keywords for the ALT text are best for it to be effective.
Here is an example:
<a href="http://www.thethinkingblog.com/2007/06/YOUR URL HERE"><img alt="YOUR KEYWORDS HERE" src="http://www.thethinkingblog.com/2007/06/YOUR FAVICON DIRECT LINK HERE"/></a>
4.) When you get a ping back from someone that has your icon in one of their “Viral Icons”, practice good karma by copying his/her Host Icon’s code (automatically the associated ALT tag will also be copied) and paste it over one of your “Viral Icons” below.
5.) Invite your readers to do the same and soon this can grow virally.
