How to delete photos in iphone photo gallery with 9 1 mobile assistant?

First, the mobile phone is connected to the computer.

1. The photos in the mobile phone don't necessarily come from the camera. At this point, photos usually come from pictures synchronized with iTunes.

2. Open iTunes and navigate to the folder where the synchronized photos are located through the browser (double-click the computer under Windows) (the image storage location is the default image storage location of the system).

3. Delete the photos that need to be deleted from the folder from the mobile phone or move them to other places. If you need to delete all the pictures at once, click Cancel Picture Synchronization.

4. After deleting the photo, click Sync to sync it once.
