Right, I'll go though this from the start :
Load the texture, and drag it out, and sort the aspect ratio
Then, zoom in to each corner in turn, and put a point.. Make sure they're all selected, and press F6
Now, go into to texture mode (a), and hit background mapping or what every it is (b)
Now, you can work as normally.. Then when you next open op O2 and your model
Select the box around where the texture should be.. Now into texture mode, and right click, and click Background From Face
It should load up exactly where it was when you pressed B
It took me ages to notice that button
