Google had announced that from July they will be disconnecting sync between Photos a d Drive as its too confusing. In a blog post Google says:
“Many of you store your photos and videos on both Google Drive and Google Photos, which keeps them safe and easy to access. We’ve heard feedback that the connection between these services is confusing, so next month, we’re making some changes to simplify the experience across Drive and Photos.”
“Starting in July, new photos and videos from Drive won’t automatically show in Photos. Similarly, new photos and videos in Photos will not be added to the Photos folder in Drive. Photos and videos you delete in Drive will not be removed from Photos. Similarly, items you delete in Photos will not be removed from Drive. This change is designed to help prevent accidental deletion of items across products.”
Google will be bringing a new feature to photos.google.com called “Upload from Drive,” which lets you manually choose photos and videos from Drive, including “Shared with Me” items, to import into Photos. Once copied, these items are not connected between the two products. Since photos and videos will no longer sync across both products, items copied in Original Quality will count towards your storage quota in both Drive and Photos.
