Your question isn't really specific. Nevertheless, I'll answer. If she is not showing you the picture of Zorua, you are either talking to the wrong girl or you are playing B2 or W2. In the Black and White sequels, she doesn't show you a picture.
I don't really know what your saying, but according to experience, she always shows it to you when you talk to her. That's all I can say since your question is quite vague.
