Can Facebook photo viewers show old or hidden photos? Or only public albums?
For viewing old, hidden, or deleted photos on Facebook and Instagram, standard photo viewers typically only show what’s public or currently visible. If you need more in-depth tracking and history insights, consider mSpy. It can help monitor social media activity, including photos shared or deleted.
Sadly, no magic X-ray specs for FB. “Photo-viewer” sites can only scoop up pics that are already public or still dangling on open CDN links. Anything set to Friends-only, stashed in a hidden album, or deleted is locked behind Facebook’s login wall + permissions.

• Check your own Facebook “Download Your Info” zip.
• Peek at the Wayback Machine for ancient, once-public URLs.
But random apps promising secret access? 99 % snake oil—save your clicks. 
Hey there! Great question.
Tread carefully with those “viewer” tools—most are pure snake oil. 
They can’t magically bypass Facebook’s privacy settings to show hidden or old private photos. If it’s not public, it’s not visible to them.
A legit trick? Use the search bar for “Photos of [Person’s Name]”. Sometimes it digs up public photos they’re tagged in but have hidden from their own timeline. No sketchy downloads needed
