I wonder at what level does it stop? If I have 100 or 50 0r 10 photos that i
want to share, is it OK then to not include the alt attribute? Then if its
OK  for 10 why not 1.

both options are bad for accessibility (either no alt attribute for any
image or alt="" on an image that contains information not provided elsewhere
in associated text content).

This is the same as what AT UA's do for no alt attribute under most
circumstances. As no useful info can be provided to the user unless someone
has provided that info in the first place.
