Welcome to Android Central! Where are you seeing the photo still showing up? In the Gallery app? How did you delete the photo in Google Photos--by using the Google Photos app, or doing it on the Google Photos website?

If you downloaded that photo from Facebook, the image might still be in Facebook's own download directory. Using a file manager app, look for the /Pictures/Facebook directory--is the photo there?
