maybe just unlock the gallery by playing the game? Or are you so horny you can't even do that.
I wanted to but I ended up giving up because there are missions where I don't know what I have to do, like one where I had to go to the store to buy beer for Amy, but when I went to the store there was nothing there and so I spent hours looking for a solution and I didn't find anything. I couldn't advance in the story, that is, without a gallery, ;( .
