Sorry, that picture is from when i changed the code for all pins to be HIGH, it is the only thing that makes a difference to the matrix


Well if all pins are high there should be no LEDs on either so you have still wired it up wrong.


I wired it up as you said with all the corrEct pinouts. 


You think you have but you have missidintified something.
What is needed is a schematic of what you are trying to acheave, not the sort of thing you have been posting so far and then a clear photograph of what you have done, along with the code you actually run not something like it.
Otherwise how else can we identify what you have wrong.
