Transfer pictures from laptop to iPhone?

Okay, so one day I woke up and all of my contacts were deleted! I restored my phone but it was last restored in august, so I lost all my pictures and some contacts but I have all the contacts on my phone that I got in august and before that. So before I restored it I took all my pictures that I KNEW were gonna be deleted and saved them on my laptop, but I don't know how to put them back on my Camera Roll. It's the updated iTunes verson.

It's easy for you to transfer pictures from laptop to iPhone with iPhone transfer platinum software which can transfer pictures as well as music/movie/Pictures/TV Shows/Podcast/iTunes U/eBooks/Camera Roll/Ringtone/SMS/Contacts/Voice memos/Camera shot files between your laptop and iPhone.

Um how do I do this
