[Typo3] header image replace techniques

[Rob De Vries]

Heya listers

I was wondering if any of you did get some good results with image 
replacements technieques.
i'm not talking about the standard header image rendering of typo.
More a CSS sollution.

The Dynamic CSS ext looks interresting.
Did anyone already do some header replacements with this, where the 
header of a content element get parsed true this ext. ?

Any feedback would be nice

Tnx
Rob
