How to scale UV map? I'm trying to position a UV map over an image and I cannot figure out how to scale the x and y dimensions independent of each other. As you can see from the picture I need to scale the y dimension to fit the eye. When I loaded the image inside of the UV editing window, the UV maps became distorted.
You do it the same way as everywhere else, by pressing S followed by the axis you want to scale on, i.e. X, Y or Z.

Additionally you can press S and then Shift + the axis you don't want to scale along, and thus scaling along the other two; So if you pressed S, followed by Shift + X, you would scale along Y and Z, but not X. This, however, only applies in the 3D View, not in the UV/Image Editor, as there are only two dimensions.
