It seems one cannot upload photos directly to Instagram from an iMac or PC. When I queried this elsewhere the advise was "You can use drop box to your tablet or phone or you can post to Fb then save to your phone." Not terribly user-friendly. Anyway, someone else popped up with the suggestion to use a programme called
Gramblr. Before I go that route, has anyone any experience of it? Good/bad/waste-of-disk-space or whatever???
