Photos and videos you move to trash in Google+ are stored for a short period of time before they are permanently deleted. If you move an item to trash, and later want to retrieve it, you can do so by following these instructions:
- Select Photos from the Google+ navigation menu.
- Click More and select Trash from the dropdown.
- Click one or many checkboxes to select photos.
- Choose Restore to return these photos back to Google+. These photos will be restored to the same album(s) they were located prior to being moved to trash. To permanently delete photos, select the items you'd like to delete, and click Delete permanently.
