A. Your iframe isnt the same size as the space that you want it to be.
B.Your whole page is an image.

Try making the page with css/html because that little design that you have behind your content area can be done as a css background image that can be positioned in the center of the page and just suffer that the letters dont go outside the table. Your site can easily be made from a combo of css/html/php/ and trial and error. Just do some resaerch. In my mind if your going to do something take the time to research what you want to do, so you know exactly what to do, and then do it. Make a work of art. This site really can be good if you take the time to perfect upon what you need. Dont rush things and do a good job so it can be something you can be proud of.
