A method and system for generating an image display plan is provided. In one embodiment, a planning system allows a user to create a display plan that specifies a sequence of images that are to be displayed and how the images are to be displayed. The planning system allows a user to specify different versions of the plan for different aspect ratios. When displaying the image, the planning system may display multiple viewports simultaneously on the image, one for each of the different aspect ratios. The planning system may allow the multiple viewports to be moved around and resized as a unit maintaining a common center point for the viewports.
