I am using the sparkels v1 theme from xoopdesign and i have the new logo/banner for the site up at top...but when you log in the admin area main menu ect are to the left of the banner and i need the banner to go all the way acroosed the page and then the admin area can start where can i find the file to change that.. if you need a visual go to http://www.glowplates.com and you will see the images i used at the top of the page but when you log in the left side turns gray and i need the image to go all the way across the page

any idea thanks
