Getting photos back onto iPhone?

[bisk]

At some point I copied off all of the photos off of my iPhone, now I've got plenty of room on my 64GB iPhone 6 Plus, so I'd like to put them back on. What's the easiest way to get them back into my Camera Roll?

I don't think you can get them in your Camera Roll, but I know you can put them in a folder/album and sync them with iTunes.

There is an app called FileExplorer Free that you can use to import the pictures to the camera roll.

Use iTunes to copy the pictures folder to the app. Then open the app, open that folder, select all the files (there is a select all button), tap the "Copy to" button on the bottom, and choose Camera Roll.
