What is the best way to store printed photos to ensure their longevity and preservation?

The best way to store printed photos for longevity and preservation is to keep them in a cool, dry, and dark environment, away from direct sunlight and extreme temperatures. Store them in acid-free photo albums or archival-quality boxes to protect them from damage. Handle them with clean hands to avoid fingerprints and use gloves if necessary. Make digital copies as a backup to ensure their preservation.
