Photos double saving in samsung galaxy s7

[AC Question]

Hi guys,

Whenever I save an image to my phone and post it on say instagram, it saves twice in my phone when I look in the gallery. This happens when I download a photo from whatsapp and so forth.

I have disabled the backup from Google+ already.

any help would be good thanks!

Are the file names similar or different?
