Josieb1 - by deleting all the opf files you have created a library which is irrecoverable should its database become corrupted/unusable. Running calibre and dropbox concurrently increases the chance of the database becoming corrupted/unusable. If dropbox syncs its copies of the opf files back to the PC then in the event of database corruption and recovery you will in all likelihood lose some of your metadata.
A Calibre library is not a single file, it is a folder containing a database (metadata.db)
and a hierarchy of associated sub folders and contents,
it must be managed as a whole - no cherry picking allowed. Calibre knows how its libraries work - Dropbox hasn't clue.
Regarding your pictures, assuming you're not using an application such as iMatch or Extensis to manage them, then comparisons with Calibre are debatable at best.
As I wrote before - to minimise risk of trashing your Dropbox located calibre library adopt the following process:
Suspend Dropbox before starting calibre. Before resuming Dropbox run calibre-db --backup_metadata command to flush any pending opf writes. Best way to that is via a script appropriate to the operating system you're using - something along these lines
Code:
If Suspend Dropbox is OK
If Run Calibre until exit is OK
If Run calibredb --backup_metadata is OK
Resume Dropbox
