      runat="server" 
      BackImageUrl="image.GIF">
    </asp:webpartzone>
  </form>
</body>
</html>

In a browser, you can switch to design mode to see the image in the empty zone. Note that an actual URL for the BackImageUrl property is not provided in this example. For details on how to change page display modes, see Walkthrough: Changing Display Modes on a Web Parts Page.

Remarks

The background image for a zone is visible in all display modes in which a zone's contents are visible. If a zone contains part controls, the image appears behind the controls. If a zone contains no controls, its contents are not rendered in browse mode, so the image is not displayed.

If the supplied image is smaller than the body of a zone, it is tiled to cover the full body area.
