Does anybody have any ideas for sending a selected image from my camera (550D in this case) to my android phone?
I can think of some sort of external rig using a small computer and bluetooth, I'd have to power it with something and probably have it have its own interface to be able to select which image I want to send. Although I have seen things set up through USB that can control options in the camera, and in turn the options in the camera can control the USB, so maybe a small script of module could be written to control the computer, an extra send button or the like.
Anybody have any other ideas? Less is more

although if you have some elaborate rube goldberg like electronic set up do share.
