Why is this app rated 12+?

The app allows unfiltered access to the Internet via the "Add Map" function, so Apple requires that I rate the app 12+ for the possibility of accessing anything on the Internet. This is why you might see a warning. It has nothing to do with anything included in the app.

How do I load files from my Mac computer?

You can put your image files (PDF or JPG, GIF, or other bitmap formats) in your User ~/Sites folder. Then go into System Preferences->Sharing and turn on Web Sharing. In the panel, you should see the URL address to access your personal website. Enter this URL into the Transit Maps app by tapping "Add new map..." and tapping the URL button, then entering the URL from your Mac. In the web page that appears, clicking on the file will load it into the app.
