Basically what Im trying to do is create a re-sizable box with curved corners. however I can't seem to get my curved images to show up properly on the corners of my box.

could someone take a look and tell me where Im making my mistake?

also I've read several tutorials on this now and there seem to be two approaches, one that uses a html border and another that uses a 1px graphic for the border of the box. is one method superior to the other? or is it basically dealers choice?
