Uncharted 4 Ending Picture - Nathan/Elena/Sully + Gold Question

[Extra_Dip_LgSoda]

Question, at the end of Uncharted 4, the kid opens Nathan Drake's mom journal with photos inside it. There is a picture at the end with Nathan/Elena/Sully sitting/standing on boxes of gold. My question is, where did they get the gold from?

Did they go back to the pirate island from Uncharted 4?
Is it from the Malaysian job where they found another sunken ship?
Is it from a previous city like El dorado?
Or from a new city they discovered (from the broken green jade with the key in it)?
Are they finally rich to fund their own research operations?
Will this lead into Uncharted 6, maybe with Sam in the lead when Nathan is retired?

I feel like for Uncharted 6, to keep the story really good, maybe we will learn more about Nathan Drakes parents? Like about his dad or mom (she could have lied about the illness and disappeared on a quest/adventure/captured).

How the dude above me says, That one is from the first Uncharted game. Also, i like the fact it never mention anything from that shi-tty ass VITA game, Golden Abyss.

i know people replied but im still going to say this. At the end of uncharted 1, Sully appears in front of Nate and Elena with a boat after they fought the final battle. Sully got it from pirates and it was filled with Spanish gold. And Sully had SPAS 12 on hands at that moment. And El Dorado isnt a city in Uncharted 1

I remember hating it back in the day on vita, it had a lot of framerate problems and felt like a cellphone knock off from Gameloft overall.
