Max # of pictures in a shared photo stream - Data usage?
Is there a limited number of pictures you can put into a shared photo stream. I know with the regular its 1k, is that the limit for the shared ones as well. Or can I create a photo stream with my entire photo library and have it all backed up on icloud.
Seperately how much data does shared photo streams use. Is it essentially downloading/uploading every photo to each device even over cellular connections. Its not a huge deal, but I'd rather not use up my data because a friend dropped 500 pictures of their dog into a shared stream. (But I do like dogs) Also does it take up space on your phone or is it all just held at the cloud level and you are essentially downloading it each time you look at it?
