PhotoPicker and WebView

Hi, I have created a web view app but it has been rejected as it wasn't "interactive and exciting" enough so I want to put a photo picker option in as well. I have entered the code and there are no errors however I can't see or access the photos as the only menu that appears is the one on the web view. Is there anything I can do to add this option somewhere so people can view the images? There is also back, home & forward buttons on the app.
