Is it possible to remove a photo when it is stuck to the glass? The glass is broken and photo only stuck in spots. Thanks. Sandi

An old fashioned razor blade is your best bet!

Step away from the razor blade!

Start by scanning. Then look around the site here, I recall several articles on how you might remove it.

Agree, always scan or re-photograph multiple times with multiple exposures before attempting the removal.

There are many threads discussing this... here are a few.
