when i click on my photos and following it is fine. But when i click on friends tab the photos doesn't show althought pager is still showing.

See on my site i opened the photos i added and ones my users tried adding are only showing red x it is not showing the picture at all.

Yes.. you are saying right..
it also does not show blog and videos too..

but i have came to know that it only display the photos,blogs,videos of last person who login (in your fnd list) only
