Hello, I am grandma Bess. 

I've just made a few pictures with my new smartphone which I would like to share but I don't know how. I better ask my grandson. 

Hello it's grandma Bess. Could you explain me how to share my picture from my smartphone?

Florian: Of course grandma.

Open the Photos gallery on your smartphone.
Select the photo you want to share. 
Tap on the share icon.
Tap "Type a name, phone number, or email" or select people to share with from the list.

You can add a message if you wish, then tap Send.

Grandma Bess: Let me see if I'm getting it right:
I have to open the photo gallery, then I have to choose the picture I want to share.
Then I have to tap on the share icon in the bottom left corner, add the email address and I have to tap send. 

Florian: That's it Grandma.
