Contact photo source file

[AC Question]

I have an LG G3 that I factory reset at the beginning of the year due to having a bunch of garbage on it. Apparently my Cloud backup hadn't saved my pictures for several months so I lost some photos that I like. I had one set as a contact photo and though I don't still have the original file that I can tell, the contact photo still shows up for that contact. I was wondering if I would be able to extract or download or find that picture because it must still exist somewhere for the contact info to still have it. Anyone know where on the phone/cloud/etc that it might save a copy of contact photos?
