That way, it doesn't matter what happens to the jpegs as you can always re-create them. If you've only got jpegs (why are you using a rubbish camera :-) then just dump the original jpegs to DVD - that's why what Google do is so bad - they compress it to upload it from your Android phone, and then delete the original! AND THAT'S THE DEFAULT !!! Cheers, Wol
