Category-Top as Thumbs?

[remethep]

Simple and easy, is this possible?
And if yes, how?

I've tried searching both the net as well as this site, but no luck.
Beforehand thanks.

It would be easier to answer with more info from you:)
By "category-top", do you mean the top category links in the sidebox, or in the categories-tabs menu in the header... or something else?
If you want to replace categories sidebox links with images, Categories Dressing will let you do that.
