A background image on html (or on body, if there is no background on html) is not zoomed by the IE7 “Change Zoom Level” functionality. All other background images are zoomed. In this test case the body has a background image with a repeating grid of squares. This box has a non repeating 100px × 100px semi-transparent green background image in the top left corner.

IE7 page zoom does not apply to the body background image
