sharing food photos

I asked 7 students.
Do you share food photos with your friends by email or any social media?
Of the 4students said they share my food photos, 3students said never share my food photos.

If you do share food photos,what photos would you share?
Their favorite types of photos are 3students said food diary and 1students said food you have created and 3students said movement with family or friends.

To my surprise, the 3students said never share my food photos.
Thank you.
