First, most of my pictures are just gray boxes that error when I try to send them and there are way too many to just go through one by one and delete them like that. Some type of management Interface is needed to smoothly manage the uploaded pictures perhaps some detection on pictures with locations that can't be resolved that show gray boxes and error.
Creation of albums should be tap a button, give it a name, description, and visibility selection ie public/private......then open your main photo gallery of uploaded photos, where you can select multiples to tag them with those album properties. Then when you send an album, it still pulls from your main gallery but only shows the person the ones tagged with that album Id. That way you only have one catalog of images...but the main issue, is that you can only upload one photo at a time. Do you add one ..then you have to go back through you're phone AGAIN.....select another photo .....crop it....hit ok....again....then hit add photo again ...then you have to browse through your phone AGAIN .. select one..... Go to the crop screen....hit ok.......YOU SEE MY POINT IM SURE......that is one of the most frustrating part of the app.
