Yeah, it can be a big help if you already have some sketches or plans of some sort of the thing you're trying to build.

Sometimes you can use them as a background for tracing curves. Sometimes they can just be a general guide to help you with proportions of where to place objects.

Let's see - there is a bit of info about how to use background images here: http://moi3d.com/forum/index.php?webtag=MOI&msg=325.1
