If you've updated to the buggy Instagram version (the first one with the Willow filter - Dec 10) your favourite Instagram helper apps can't seem to upload anymore. Unless, you know the workaround!
Of course, if you want or can, update to the latest Instagram app (Dec 20 or later) - problem solved! If not, read on...

BUT, even though there seems to be no picture, HIT _NEXT_ ANYWAY
