Help with Responsive Pro Home Page Image

I am using the responsive pro theme. The home page for this theme basically has two columns. One side has text and a button and the other has a picture (visit http://www.1stchoicehomebuyers if you don’t understand my description). I am trying to place an image that is centered (not to a column, but the whole page). This is the code that is generated when I upload it– this code places the picture only on the left column and not centered to the page. Anyone know how I can alter the code to fix this??

<p style="text-align: center;"><a href="http://www.1stchoicehomebuyers.com/wp-content/uploads/2013/10/Blank.png"><img class="alignnone size-full wp-image-120" alt="Blank" src="http://www.1stchoicehomebuyers.com/wp-content/uploads/2013/10/Blank.png" width="832" height="374" </p>

Any help would be greatly appreciated!!

Thank you,
Ashley
