My Lumia 650 / win mob 10, do not recognize some, just some, jpg attachments of emails.

from time to time, jpg attachments are not open. For example, today I received 2 emails, from the same friend, each one with a picture. One was recognised, one not.
Lumia 650, win mobile 10.
I keep my old Lumia 925/win phone 8.1 - with the same accounts - the problem do not exists.
