Picture border around infobox

[lepracaun]

Hi there

 

I want to change my infoboxes so that it looks like this:

 

Now I got the top to look like that, but can anybody tell me where to change it so that I have the side(left/right) and bottom border/pic to look like in the picture?

 

I also need to change the text to black(Catalog, Whats New etc), but can't find it in the stylesheet.css - can anybody tell me where to change it in the stylesheet.css so that it is black and not white.

 

Thank you
