I am creating a site and have to use the following graphical layout that can be seen at this link: http://www11.brinkster.com/ksuchoc/Sample/Sample.html
I am not concerned about the left bar what i am concerned about is being able to use as much of the white space for text as possible. Having the curved blue line at the bottom eats a lot of space up, I would like to either cut up the graphic or something to that effect so that I can utilize as much of the white space as possible, although the bottom graphic is actually 3 graphics side to side. What can i do?

Help is greatly appreciated.

Samples would be good.

Thanks to all that reply.
