Sigh. Why is it that people sometimes get so close to great and then fail.
Apple photostream is nearly wonderful but feels half implemented. The main issue is that while sharing, u only get low resolution images.
The sad thing is they do store the original resolution somewhere but other users can't access it even on a PC or Mac. Seems like a one line pointer change but oh well. Back to the drawing board on simple sharing.
I've tried FTP sites, private web sites and this is so convenient (nearly!) because it pushes the photos and is installed by default on iOS at least
With shared photo streams, however, the situation is a bit different. Apple states that "Shared Photo Streams deliver photos in a device-optimized resolution that speeds upload and downloads and saves storage space", and therefore the photos are not uploaded to the server in the original resolution
