How to import pictures from computer to iphone?

I have a lenovo laptop and i'm trying to import pictures that are saved on it from my old iphone, which was stolen. I have my new iphone plugged into my laptop but i'm not sure how to get my pictures onto it?

You would have to sync them over. If you know where the photos are on your computer. First you would install itunes and then connect the phone to the computer. Then in itunes select the phone. There will be a photos tab, you click on that and you can sync photos to the phone.
