At the bottom left, click on the " Share "
On the bottom taskbar, scroll down and select the option " Hide ".
Click " Hide Photos " (or Photos) in the pop-up to confirm.
Subsequent photos are no longer on your main album and stored in an album called "Hidden". To access them, go to the "Albums" tab of the Photos app. Then scroll all the way down until you see "Hide" listed under "Utilities".
Once you've moved a photo to a hidden album, you can hide the album, removing it from the Photos app. Here's how to do it:
Open the Settings app .
Scroll down until you see the " Photos " app listed and select it.
Scroll down and swipe the "Hidden albums" switch to the left, turning it from green to gray.
Now, hidden albums will no longer appear in the "Utilities" section of the Photos application. To show the album again, just go back to Settings and turn the "Hidden albums" switch back on.
How to lock photos on your iPhone in Notes app
If you want to hide your picture completely outside of the Photos app, you can do so with the Notes app. Here's how to do it:
Open the image that needs security, then click on the "Share" icon.
On the list of apps, scroll right until you see the Notes app icon and tap it. Draft Notes will appear with the image in them - choose a Notes folder to save and hit "Save" in the upper right corner.
Open the Notes app, then open the note with the picture in it. Tap the three-dot icon in the upper right corner of the note.
In the pop-up menu, select " Lock ".
Then enter the password, verify the password and create a hint in case you forget it. Click "Done" in the upper right corner. If you've locked notes before, Notes will only ask you for the password you used to lock the note.
Now a padlock will appear in the top right corner of your note. To lock the note, tap the padlock icon and the note will disappear, with the message "This note is locked". Click on "View note" and enter your password any time you want to view notes. Whenever you finish viewing the note, be sure to tap the padlock icon again to seal the padlock.
Finally, make sure that you removed the original photo from the Photos app so that it's only in the Notes app for now.
If you don't want someone to find the image in the Photos and Notes app, send yourself the photo or make a note via text message, then remove it from your photo.
Unless someone steals your messages, it's hard to see.
Note: It's recommended to sync Photos and Notes when you switch to a new iPhone to avoid losing hidden pictures.
