Hiding photos on an iPhone can be quite handy for privacy. You can use the "Hide" feature available in the Photos app by selecting the photo(s), tapping the share icon, and choosing "Hide." These photos will move to a hidden album, though it's not password-protected. Have you tried this method before, or is there a specific reason you're looking to hide photos on your iPhone? If you're looking for more secure options, there are third-party apps too. Let me know if you want to explore those!
