How to transfer photos from Windows 10 onto my iphone?

I tried searching it up online, but all i got was how to transfer photos from your iPhone to windows 10, but i want to know how to do the opposite of that. When i plug in my iPhone, they only give me an import option to move photos from my phone to my computer, but no option to do the opposite.

How to go about making an overhead camera from the wall?

I would like to start out basic using simple devices like my iPhone and Flip UltraHD and record videos from above using a boom arm or something of the sort screwed to the wall. It needs to extend roughly 40 inches, but I can sacrifice some length if it means saving a significant enough amount of money to justify doing so. Having it mounted on the wall would be ideal for what I plan on using it for since I need the room.

I'm mainly wondering two things:
1. Is there any best way to go about doing this? I'm very unfamiliar with the hardware needed to bring these different pieces together, which leads to my second question…

2. How do I attach an iPhone and/or Flip at the end? I'm asking this because the tutorials I have seen have only used what I can only imagine to be high end camcorders, and I would think such devices connect differently than if you were to just use your phone. I know there are iPhone holders for say, tripods, but I don't know if that is what I would need or how I would connect it all together.

Apologies for my noobishness.

Should I get a Mac? Pros and cons?

I own a Windows 8 (recently upgraded to Windows 10). And I've been a pc user my whole life. Now I want to switch to Mac. Honestly I don't know why, half of me is telling me that yes definitely get it! But the other half is telling me that I just want it for a ego booster. Also I like the sound it makes when you click lol.
