With the release of iOS 6, Apple has added support for
file types that accept images or videos:
<input type=file accept="video/*"> <input type=file accept="image/*">
The resulting forms will allow you to select a new photo or video from an existing photo stream or make a new one right then. Developers don’t get to control the camera or it’s functions like they would in a native app but this at least allows users to capture or select a photo.
