Instead of the banner on the bottom of main page, try some rectangular format, which would be similar to the frames that hold links on the page.

In the top box put an no-outline Adsense ad with the same color background as the rest; in the bottom box, put the Wallpaper of the Week. Where the Wallpaper of the Week is now, put Last Week's Wallpaper of the Week.
