I don't see why you'd find the graphics cells to be square. That's not my experience and it's easy to set a certain aspect ratio: Plot[x, {x, 0, 1}, AspectRatio -> 1/10] Any picture that I import is shown in its original aspect ratio. So I really don't understand your problem. Your editing of the .nb file in a text editor seems unnecessary. You can set all options using the option inspector in the Format menu. The aspect ratio can be set in Formatting options/Expression formatting/ Graphics Box options/GraphicsBoxOptions/AspectRatio.
