Deleted photos keep reappearing

[AC Question]

I've deleted about 100+ photos under the main photo thing that comes with the phone. I think it's Google. Mostly because I need space. Then I empty the trash can. Days later I'm low on space again. Sure enough all the deleted photos are back. I've done it probably 30 times over the past 2 months. Usually the same pictures. I looked it up and saw another had the problem and was told to delete with the Google app on the phone. But that's what I've done, over and over.
