infoboxes with rounded corners

[killerwhale65]

hi,

 

I am having some troubles with making rounded corners for my infoboxes.

 

I am using 2 images: 1 for the top, and 1 for the bottom. Additionally i give the infobox a 1px border left and right.

 

The problem is the bottom pic (the rest works good): i don't know where to place it. It never looks right. Mostly i see the left and right borders from the infobox-class continuing next to my bottom picture.

 

Anyone who could give me some hints on this matter?

 

Many thanks!

 

Matt
