How can I safely remove photos stuck to glass without damaging them?

To safely remove photos stuck to glass without damaging them, you can try using a hairdryer on a low heat setting to gently warm the adhesive and carefully peel the photo off. Another method is to place the glass in a plastic bag and then in the freezer for a few hours to help loosen the adhesive. Be patient and take your time to avoid tearing or damaging the photo.
