It's not about the photos. It's about what happens afterward.

Last time I checked, we still live in a free country. Problem is, Afghanistan isn't.

This means you're going to have to get creative...

What if you took the series of photos and made just one that isn't "objectinable" per local standards. Just send that ONE picture and attach a note that says, there are more pictures he can see when he gets home.

Not saying this is THE answer. Just saying that you should think "outside the box" on this.
