Gain 20 dollars at the drink mixing station,(or however you want), then goto Fat Sam's T*tty City. Pay the bouncer the $20 to play the "nude spanking game" and win the "nude spanking game".
Then once your back out in the stage area, zena the dancer on stage, will be topless. Use your camera to view her and she will pose for you causing the "good shot" meter to light green. Snap six pictures of her with the green light showing, and exit "T*tty City". Go down the block to Sweetwater the pimp and sell him those pictures, he will pay you between $140 and $240. Not a bad return on a $20 investment. Plus even if you lose the spanking game the dancer has the best...ehhum..."graphics" in this game.
