how do i transfer pictures from my pc to my ipod?

So, I went to a concert on the weekend, and used my husbands iphone for picture taking (as my ipod doesn't have a flash). Now I've uploaded the photos taken on his iphone, to our pc....and I want to transfer them to my ipod touch. Not sure how to do this? I am sure it's simple...any help would be greatly appreciated! Thanks so much 🙂
