Cleaning up references to non-existant images

[ChrisW-B]

Hey, I recently made some mistakes while troubleshooting a self hosted bookwyrm, and one of them was completely cleaning the remote bucket where images were stored. I've since fixed everything, but I neglected to backup the bucket first, so now my instance has a lot of pointers to images that don't exist.

Is there a safe way to tell bookwyrm to re-fetch and store these images? They're not around locally, so I can't sync/copy to s3. I'm imagining that I'll likely need to clear a DB column or something similar, but I don't want to actually break things, so I figured I'd ask here before poking around in there.

Thanks for any help, and no worries if this isn't possible- eventually my feed will be all new books and this probably won't be much of a problem
