How can I remove a photo that is stuck to glass?

To remove a photo stuck to glass, you can try soaking the glass in warm, soapy water to loosen the adhesive. Gently peel the photo off once it has softened. If that doesn't work, you can also try using a hairdryer on a low setting to heat up the adhesive and carefully peel the photo off. Be patient and gentle to avoid damaging the photo or the glass.
