Abstract
Disclosed is a system, method, and program for magnifying displayed content downloaded from a server over a network. Information is received indicating selection of a region of the displayed content to magnify. A determination is made of at least one region of the selected region including image content. The server maintains a high resolution file version and a low resolution file version of the image content. A determination is then made as to whether the selected image content from the displayed image file is the low resolution file version. If so, a command is generated to retrieve from the server specific byte locations from the high resolution file version including the image content in the selected region. The specified bytes are less than all the image data bytes in the high resolution version of the file if the image content in the selected region comprises less than all of the image content maintained in the high resolution version of the file.
