I'm not sure what you're asking, but if you want to import an image to model from, there are a couple of ways. I will give you the simplest way. You can do it by going to your work window and doing as follows:
Go to "View > Image Plane > Import Image". You can then import any image you like. Of course, you'll want to import a front view picture to your "Front View" work window, a side view to the side window, &c.
That's really all there is to it!
