The following recommendations are included in Preserving Your Digital Memories from the Library of Congress:
At Risk: Digital Photos
Family memories and special events that future generations would value are increasingly documented as digital photographs. But 10 years from now current memory sticks and cameras will most likely be obsolete, trapping the images in unusable or unsupported storage media.
Tip: Digital Photos
Because digital photographs require specific hardware and software to view, it is important to migrate files to the latest storage media using freely available formats. Make several copies of digital photographs and keep them in different places. To help manage your photos, it helps to label the photos with easily recognizable names and to embed tags and other information in the photo files. Saving copies of your photos on Web sites and printing copies with archive-quality ink and high-quality paper are also options for preservation.
