Hi Tirthurin - I too live in a country that cannot see individual BR show. Like you, I can only give a view of what I see in the painting BUT that is a huge start for people trying to identify pictures from the tabs. They might not be able to use the full range of tabs, such as guest painting etc, but being able to identify them using about 70% of the tabs will be a great help.
It is very important the more than one person gives their views on the tabs as different people see different things, such as is a painting showing Spring, Summer or Autumn?
Have a go and give it a try, you are not committing yourself to reviewing every single painting or within a fixed time. Your efforts will be, hopefully 8-), appreciated by members.
