Find where contact photo data is stored to recover photo

[AC Question]

So I have a photo on one of my contacts which I desperately want the photo back. I lost all my photos on an older phone, but this one is still being used for a contact on my Samsung S5.

Can anyone tell me how to go through the folders to recover the said photo?

If it helps it was from a photo I took with the camera and then uploaded into the contact a long time ago?

Thanks!
