Photos won't delete from gallery or SDcard

[NickWBurns]

I'm trying to delete photos from my gallery and when I do, they appear back in the gallery immediately. When I use ES File Explorer I find my DCIM folder and delete them from there and the photos disappear but only for a little then they appear back in both places a short time later. I have my google photo sync and picassa sync off and I've deleted all my photos from both as I don't use them. All my pictures are stored on my SDcard and i can't figure out why I cannot get rid of these pictures. Thanks for your help
