Abstract: A method, apparatus and computer program product are provided to cause different multi-dimensional representations of an image to be presented upon a display and to facilitate changing from one multi-dimensional representation of the image to another multi-dimensional representation of the image, such as in response to a change in the shape of the display. In the context of a method, a first, multi-dimensional representation of an image is caused to be presented upon the display while the display has a first shape. The method also causes a second, multi-dimensional representation of the image, different than the first, multi-dimensional representation of the image, to be presented upon the display while the display has a second shape, different than the first shape. The method also determines the shape of the display such that the corresponding representation of the image is caused to be presented in response thereto.
