Orphan images, which were not approved

As part of testing, a new user signed up. He submitted an image for approval.
Then, the user was deleted. Now, I cannot approve or reject the images.
Any advice will be highly appreciated.

How did you delete the user? Image fields have a cleanup process. It only works if you properly deleted them through CB. If you delete them through Joomla that cleanup process never happens.

Good to know that. I will make sure I always use CB User Management. Thanks.

Now, to fix these orphan images, should I delete these records from the db? If yes, where can I find them? If no, is there any other way?

Thank you very much for your help... ...

You can try running user synchronization within CB > Tools which should clean up those orphaned rows in _comprofiler. Don't know if it'll clean up those images though, but you can try. Otherwise you'll need to manually delete the orphaned images.
