Large Image Viewer opens very large images. The keys '+' and '-' perform magnification and reduction. The keys Option-'+', Option -'-', Control-'+' and Control-'-' provide further magnification and reduction ability. The arrow keys translate the image. Option and Control aid the arrow keys with translation. The user may also drag the image with the mouse (drag and drop is not yet supported).
Large Image viewer will open very large images, such as the Hubble Space Telescope Largest Galaxy Portrait of the Pinwheel Galaxy, M101. The largest TIFF file of this image (15852 x 12392, 442 MB) is available at
Large Image Viewer will need a few minutes to open this file, depending on your Macintosh's speed and available memory.

Thanks go to NASA and the Hubble Space Telescope team for the M101 images. The icon for Large Image Viewer is derived from these images. These images are in the public domain under Contract NAS5-26555. Please see http://hubblesite.org/copyright/ for more information.
The Hubble Space Telescope was built by Perkin-Elmer and Lockheed, working under the direction of the Marshall Space Flight Center. See Hubble Space Telescope - Wikipedia for more information. Thousands around the country contributed to the construction and operation of the Space Shuttle program. And, last but not least, thanks go to the astronauts who left the comfort and safety of home and family to go to space to launch and service Hubble, so that mankind may enjoy these images and the science that we learn from Hubble.
