Storing data in the app sandbox - what if the user runs out of space?
<p>I am storing some images locally in my app's sandbox. I currently have the minimum set at 10MB, and will be allowing the user to choose how much storage is allowed (up to 500MB).</p>

<p>In the scenario that the app is installed on a device where there's simple no space on it, or if there's 1MB space left and I start saving a 2MB image what happens?</p>
