The the client side of a content provider consumer I can do something like this, to get a proper InputStream for reading the picture:

This is tough. You might be able to get away with using anything that can use a Socket interface. I haven't done it, but this is what makes me think so:

And a Socket could, in theory, be an Internet resource, or most anything...if you're willing to work at the Socket level. I would probably just give up and create the temporary file. Perhaps that makes me a coward.
