Hi Jeff - off on a tangent there 
If you are going to document file handling, Media and Non Media, that would be great. I suggest you read @Anke Guide on the subject and get her permission to publish her chart - a picture paints a thousand words, it makes the subject of Android files much easier to understand.
The CloudDB documentation certainly needs instructions for use with image files. If anyone at MIT has the time, it would be even better if CloudDB could be enhanced with dedicated Blocks for uploading/downloading image files. This would make it easier to understand.
