Moving a selected thumbnail image parallel to a linear strip of unselected thumbnail images within a preview electronic display, increases spacing between two of the adjacent thumbnail images, when the selected thumbnail image is positioned proximate them. In turn, spacing between other adjacent ones of the unselected thumbnail images returns to the original spacing, when the selected thumbnail image is not positioned proximate them. Methods and systems return the unselected thumbnail images to the original size in response to releasing the selected thumbnail image between two adjacent thumbnail images, within the movable thumbnail electronic display image, and this changes the linear strip of original size thumbnail images of the document pages from an original page order to a different order having the selected thumbnail image in a different location within the linear strip.
