Friends can't see my tagged photos on facebook?

okay so A and B are both my friends and C is also one of my friends but is not friends with A or B. C cannot see my tagged photo in B's album but C can see my tagged photo in A's album but not the rest of A's album just the tagged pictures of me. A and B both have their privacy settings set to "only friends". This is very ennoying because some of my friends can only see half of my tagged pictures. What can I do?
