Hi, I am not really sure I understand your question, but perhaps I can help you. You spoke of "rotating the image" then "rotating the object". The thing to understand about UVs is that they are in a different universe from vertices, faces, and edges. Rotating your object in your perspective view will have no effect on your UVs.

Now if you rotate your image in photoshop or whatever 2d graphics program you are using, the UVs will not really move, they will just sample the image in a different way.
