Is your feature request related to a problem? Please describe.
Usually i describe my pictures in keywords on the EXIF. I've seen that there is an option de label Picture on, that look like is doing what i'm looking for.

Describe the solution you'd like
I'd like Nextcloud to scan EXIF Keywords and made label with them. And put the label on the exif file when it's created on the cloud.

Thanks for all the job done!
