For what purpose? For all the same purposes as taking it live. Just another option, and a common one in native app land. Pick a picture or take one. You get the idea. >>- image destination (local to app, to the SD card, filesystem, as base64 string) > > In the W3C the Blob is the best we've got for a generic transfer mechanism. There are already established ways of extracting data from a Blob via the FileReader API [4] (dataURI, string, typedarray, etc.). The Streams API proposal [5] also lets you do most of the same for a Stream content (including extracting chunks into Blobs). Right.. we've implemented FileReader/FileWriter too. We also added a few other goodies such as FileTransfer which is sorta like XHR2 (but predates it). Anyhow, point is, those cases come up in the installable web app world. Sandbox or no.
