Messing with Adsense Code

I want to do like digitalpoint did with there adsense code. A way to update my adsense on every page just by changing one thing so I can have a .gif banner there or adsense code or what ever I want by changing one thing.

have this code in all my web pages

<link media="screen" type="text/css" href="style.css" rel="stylesheet"

but instead of it referring to my css style sheet it goes to my .gif code or adsense.html or whatever I don't know.

 

hey be careful with that i think you can get banned from adsense for messing with the code

 

Whenever you do, check your raw html code to make sure that the adsense code is exactly same as the original.
