another photo that wont let me use

I am trying to do simultaneous transition on firefly with prompts.. but it doesnt let me use my photos that i have taken around the world. they are phjotos of abandoned places. it is my art and i would like to be able to use them!
they dont violate your guidlines nor they anything. its simply abandoned ruines. my whole photos are the same and its not nice to not be able to use them. 
please try to fix this.
its very irritating and discriminating
