At least one signal bearing medium (106, 130) tangibly embodying a program of machine-readable instructions executable by a digital data processing apparatus to perform operations to manage an interactive display system including a touch-sensitive display, the operations comprising: establishing (232, 234) a first image and at least one secondary image, each image representing a region having various spatial coordinates, the spatial coordinates overlapping at least in part such that each image comprises an alternate depiction of subject matter common to all of the images; presenting the first image upon the display; responsive to prescribed user input including contact with the display, performing further operations comprising: updating imagery presented by the display to integrate a region of at least one of the secondary images into the display; where each integrated region has substantially identical represented coordinates as a counterpart region of the first image; where each point on the display continues to depict imagery corresponding to the same spatial coordinates regardless of which image is being shown; the medium being characterized by said operations further comprising: receiving the prescribed user input, which comprises detecting occurrence of contacts at at least first and second contact sites on the display; defining a swipe area upon the display, the swipe area bounded by the first and second contact sites; the operation of updating imagery presented by the display to integrate a region of at least one of the secondary images into the display comprises: within the swipe area, ceasing display of the first image and instead displaying one of the secondary images; maintaining display of the first image outside the swipe area. establishing (232, 234) a first image and at least one secondary image, each image representing a region having various spatial coordinates, the spatial coordinates overlapping at least in part such that each image comprises an alternate depiction of subject matter common to all of the images;
