Many thanks for the help. I'm very much appreciated. I deleted the spaces in the image now. I also take out the table in the banner section. The reason I put a table there is because the final page will have a five piece of .gif images that made the logo. I couldn't see any other way to handle 5 pieces of images that made the logo so that is why I used table. But to find out what's wrong with the layout, I've deleted the banner table.
According to what I've calculated, the leftsideMenu is 133px, rightsideMenu is 123px, and so 775px - 256px = 519px available space in the center. However, when I do this 775px - 150 px margin left = 625 px and then subtract 130px from the right I get 495px. So the 519px center space should be plenty of room for the 495px mainContent section.
