How to transfer photos from laptop to iPhone?

I have Windows 9 (I think) on my Asus laptop and an iPhone 6s and I want to transfer a photo from my laptop to my phone.

I've looked at other answers and I see something about syncing changes with iTunes, but there's no "photos" or "pictures" tab on my iTunes store on my iPhone and I don't have iTunes on my laptop.

I would really appreciate it if someone would help.

Am I able to exchange my iPhone 6 for a different color with T-Mobile?

So I had the iPhone 6 in space grey. The screen cracked so I had it replaced with T-Mobile Jump program. So I called so they would send me a replacement. And they sent me the iPhone 6 in gold. So is there any way I can exchange it for the space grey at T-Mobile? I really do not like it in gold. I still have the box from my first iPhone 6 and the packaging the replacement phone came in if that helps.

IPhone 6 plus 128gb vs iPhone 6s plus 64gb?

I recently got my iPhone 6 plus in May last year as a gift. This year I got a 64gb 6s even though I wanted the 128gb. :/ The 6splus is pink and 6 plus is silver. I wanted to give which ever I don't use to my mom. Which one do you think she would like?

What's wrong with my phone? (Iphone 5c)?

Today I got the screen replaced on my iPhone 5c as the led screen behind it had broken two days ago (I dropped it) Before this, my phone was perfect except for a crack in the left corner as a result of dropping it. I got my phone back today and now it's restarting every minute and whenever I go into any app, the phone freezes completely and then restarts. Also, when I go I to my gallery, all the pics are gone but when I press down, a photo pops up (the screen is still white) and it says "loading" on it. But yet when I go into the collection part, all the photos are there. When I try to delete one of these tho, the gallery turns off and the phone restarts. Does anyone know what's wrong with my phone?
