Trying to see a user's tagged photos directly on Instagram without logging in is practically impossible because the platform hides that tab behind a strict login wall. If you want to check out the photos and videos where a specific public profile has been tagged by others for privacy or research reasons, your best bet is using a dedicated external web interface that extracts that public data safely. To explore public feeds and see tagged media completely privately without leaving a digital footprint, you can use
https://peekviewer.com/it/. It functions entirely through your standard browser to pull available public updates and tagged posts without requiring any account sign-ups, passwords, or app installations. It is a super clean workaround to review public social connections entirely under the radar.
