Most mainstream NTs from my experience socializing with them, like to mainly talk about things that are media/socially orientated, such as:
Fashions, Trends, Entertainment, Current Affairs, Weather, Local Issues, etc whatever the Media is shoving down their throats mainly.
Or simply personally related to them or someone they know, like:
What they've done, what someone else did, what they do for a living, what happened to them on the weekends, etc
If you try to get into a conversation with them that's more complicated than that, that's when it becomes a problem. I've confused a lot of NTs with the complicated concepts I would like to talk about, so I refrain from doing so because it's pointless. In my strategy, I just stick to what works in society and talk about casual matters like NTs do. I occasionally throw in my complicated concepts or views at times, but only when the conversation gets deeper and that's not very often.
If you want to talk with most people but want to say things about what interests you; you should filter the level of detail of anything you say to them. There's one rule of thumb to follow when someone asks you a simple and social question, and that is to give a simple and social answer. Also it's good to add a question after your answer to provoke more conversation; unless the person doesn't look interested after you said the answer.
To use the situation you presented as an example,
Instead of:
It's "Iwojima", a statue of men placing an American flag. I took photos and have them somewhere in my messy desk.
I recommend:
It's the "Iwo Jima" statue, I also have taken photos of it in real life. Have you also seen any landmarks in real life?
The problem is that, you'll need to try to experience this strategy and refine it until you find it easier to socialize with others. It's not guaranteed to work for complicated talks, because unfortunately as I stated above, it's mostly about media/socially orientated or personal discussion when it comes to socializing NTs.
