Hover over IMAGE Effect

I found out how to create my very own attractive Simple Rollover Buttons and Images. So when you hover over the image, another image is then displayed.
You can see an example hereand also create your own. Below is the code and if you would like to customize it go here.
If you know or have any other cool examples please show me!

 

Eeew. Why would you inflict that on yourself deliberately? What happed to clean, accessible CSS?

 

Yeah, CSS would be much better for this.

 

Why is css better for this?

 

It works for those people with Javascript disabled, generally uses less code and much cleaner. This is what CSS was designed for - presentation. Javascript is unneeded.

 

because css will give you clean code which is seo friendly and search engines love clean code

 

thanks for the lecture!
But cmon... that's still pretty cool what I got here.

 

Well atleast I think it's cool...
