Quote - So the question is, should I remap or leave it as it is?

I don' really feel qualified to voice an oppinion on whether to remap it or not. I suppose it depends to a large degree on wether BluEcho and RAMWolff have already invested much time in working on the orriginal mapping, or whther they are yet to start. I sugest you go with whatever they say.

I do have an oppinion on the diagonal versus horizontal placement of the map though. As bob1965 said you could rotate it 45, then rotate it back, but in my experience rotating seriously degrades the quality of an image. So if you do remap, I would go for a vertical placement.

You are correct in that rotating does degrade quality unless you are using a nondestructive editing environment.

Additionally Photoshop allows you to rotate the workspace, much like you would a sheet of paper, without affecting the image resolution.

The above points are the basis for my comment, I made the presumption of nondestructive editing tools being used.
