Wow, you should seriously consider recoding all of those tables in to some clean DIVs. You've got like 5 nested tables right around the news box that makes it near impossible to tell what is going on.

Anyhow, I digress. The problem is that the image is 184px wide while your box is only 170px wide. The curves are there, but they are outside the bounds of the table.
