Sources close to Vanessa Bryant tell us she is "furious" and "embarrassed" over the photos -- one of Kobe chatting up 2 women at an afterparty last week in Barcelona ... the other showed him hanging with 2 different women in a nightclub.
But we're told Vanessa's anger is NOT because she thinks Kobe cheated ... instead she's mad that he put himself in situations where the photos could be taken.
