Transfer photos without backing up the iPhone I wanted to transfer a few photos from my computer to the iPhone and I though: lets do it quickly in a couple of minutes!

It was quite sad to realise iTunes only allows me to transfer photos into my iPhone 7 if I mark the checkbox "Sync Photos". 
The, for a very strange reason, iTunes starts doing a backup of my iPhone when I click on "sync" in order to transfer the pictures.

Las backup I did took around 3 hours. And I definitely do not want to wait 3 hours to transfer 10 pictures...

Can someone explain me what am I doing wrong? 
Because I seriously expect to be doing something very wrong... otherwise I ca not believe how bad Apple designed iTunes and the transfer of pictures/video.

I was forced to use Google Drive to transfer 10 pictures... quite sad...
Try AirDrop.

It's a very simple way to transfer any kind of files (not just photos) between devices. Just select the pictures, right-click them, select Share > AirDrop, and pick your iPhone. Make sure it's unlocked, or it won't show up.

Important note: To use AirDrop between Mac and iOS, your mac needs to be from 2012 or later (but not the mid-2012 Mac Pro) and running OS X Yosemite (10.10) or later, and your iPhone needs iOS 7 or later.
