Hm - although it is indeed possible to simply use the background image type to display an image, an HTML based solution may work best. By utilizing MediaLab's ability to render background HTML items and custom items, you should be able to easily integrate any layout required with these images. This task shouldn't require too much coding at all to setup. For more information on custom items, see the following link:

Try reading up on the information provided above, and definitely let me know if you still need help. I would be glad to get you started.
