Have labels written on photos appear on the item name itself, for example you had a pile of photographs of different events in the same location and you used 'count photo' instead of just being
first photograph of X
second photograph of X
third photograph of X
fourth photograph of X
it could be
first photograph of X - bob's concert 11/2/09
second photograph of X - Halloween party
third photograph of X - movie night 15/2/09
fourth photograph of X - blah blah blah
