Ok, so you can deleted safely the unused ones with the SQL commands.
As for the *physical* files on the server (usually 
/var/lib/glance/images), you need to check that against the Glance 
database:
`select UUID where deleted =1`
You will retrieve a list of unused UUIDs, and these files can be removed 
as well
