After choosing your image you'll be taken back to the Viewport Background window. Here, you'll have to change a few options to make things easier. In Aspect Ratio, change to Match Bitmap and enable Lock Zoom/Pan. Close this window by clicking on OK (Fig.05)
The image will show up in the viewport and we can zoom in without getting the image static on the viewport so that it now goes along with the zoom and pan. Notice that the image must match the selected viewport (Fig.06)
Right now the image is in the viewport, you should repeat the process for the remaining viewports (Fig.07)
Another way to add the images to the viewport is to create four grids in their respective axis. This was the technique I used for this model (Fig.08).
Here is an example of a blueprint used for the modeling of my Mustang Shelby. For realistic inorganic modeling it's imperative to use one of these. Blueprints can be acquired for free at www.the-blueprints.com (Fig.09).
