Abstract
In accordance with one or more aspects, a variable resolution image is displayed at an initial resolution. The variable resolution image has multiple portions, at least two of which have different resolutions. A request to display one of the multiple portions of the variable resolution image at a higher resolution is received, and a check is made as to whether a higher resolution version of the one portion is available. The higher resolution version of the one portion is displayed if available, otherwise the one portion at the initial resolution is displayed.
