Can I do a standard restore/recover using image file backups? We have a database backed up with incrementally updated image file backups.  I understand the typical use case would be to switch to the copies, but would a point in time recovery using restore/recover also work?  I'm considering this route because the storage for space for the copies is slower.
I believe the answer is Yes.  Here is the supporting evidence:
