TMZ broke the story ... Wiz is gearing up to demand an increase in the amount of time he gets with their 1-year-old son Sebastian -- and we're told these photos will be part of his case.
One of the images shows dog poop strewn across a backyard patio. As we told you one of the complaints from Wiz's camp is Amber's dog eats its own feces and then licks Sebastian's face.
Other pics include a knife left out on a counter top and loose garbage in the yard.
Amber hasn't responded to calls for comment. She's been kinda busy ... much like Wiz.
