The problem is these have not been directly designd for import/export without the use of a computer so what you end up with would be the requirement of a photo bank/drive which would need to be powerful enough for the Bloggie.
You have two different types of devices, one which can use its internal power to leave itself switched on and the other solely takes power from the external power source when connected. If that makes sense? The Bloggie is the latter so on its own connected to some sort of flash or external drive will simply not give any response/recognition.
It may be possible that we see these on later models but I do not predict an update on this any time soon to change its USB operations.
