This is fantastic, better photo viewing is the only thing I was missing from Nextcloud, since without this I basically can't see any photos (they're too slow and the UX is bad).

I installed this, indexed the photos, etc, but I still get lots of grey boxes (photos not loading) when I browse. Am I missing something, or is my server just too slow for this?

EDIT: I think my server is just too slow. The entire machine freezes when loading one of the photos.
