User’s Guide: Help With Images
Most prints and photographs on the Library Web site are displayed in GIF and JPEG formats and require no special viewers. Some images are also offered as TIFFs—higher-resolution images with larger file sizes. Although most browsers support display of jpg and gif images, an external viewer or plug-in is required for viewing TIFF images. Imaging for Windows® offers users basic desktop image viewing including TIFF files. Developed for Microsoft, it is currently included as an accessory in every copy of Windows 95, Windows 98, Windows NT, Windows 2000, and Windows XP. Since it is part of the standard install, you may already have Imaging for Windows® installed on your desktop. To find out if you do, click on the “Start” button, select “Programs” and then “Accessories” and look for “Imaging.” Early versions of Windows 95 did not have this software and users of this version of Windows can download it free of charge.
Various other programs are available for viewing TIFF images. Follow the links below to see options for viewing TIFF images.

OSX: locate "Preview" on your computer

Sometimes, individuals have difficulty opening TIFF files. One possible explanation for this is that the file is large. (Many TIFF files exceed 10 megabytes, and some are as large as 190 megabytes.) It can take a long time to open a file if you are using a dial-up connection. You may want to try saving the file without first opening it.
Another TIFF downloading problem may occur if you have QuickTime® software. If after waiting for a TIFF file to load, you get what looks like a piece of torn movie film, you have encountered QuickTime unsuccessfully attempting to display the TIFF file.
QuickTime tries to read TIFF files, but it can't read all varieties of TIFF files, including some found on the Library of Congress Web site. To correct this problem, you will need to instruct QuickTime to stop trying to display TIFF files. Once you've done this, your TIFF software should start working.
Here is how to disable QuickTime for the purpose of viewing TIFF files with a different software tool. A side benefit is that after following these steps, you are free again to assign any valid TIFF player to Web browser software.
- Play a QuickTime Movie with the QuickTime Player. A short one is available here: <http://memory.loc.gov/mbrs/edmp/4051.mov>.
- At the right end of the navigation bar (below the movie window) click on the small down arrow. Click on "About QuickTime Plug-In" and make sure you have version 5 or higher. (If not go to <http://www.apple.com/quicktime/download/> before proceeding with the rest of the steps and download and install the latest version. Then return to these instructions and begin again at step one.)
- Click "OK," and then click on the down arrow again
- Select Plug-In Settings
- Select MIME Settings
- Double click the TIFF entries until the plus-signs there go away.
- Now try the TIFF file again. It should work with the TIFF software on your computer if the TIFF file format is properly "associated" with your Web browser. (For a list of TIFF viewers, see: http://memory.loc.gov/ammem/help/view.html#photograph )
