Sorry but I have no idea what you are talking about
So the pictures now all in iPhoto imported -
Ok you state that the photos from yoru photo stream have ll been imported into iPhoto
but not in the folders i created
Since Folders in iPhoto do not hold photos this makes no sense - when PS photos are imported to iPhoto they go into an event named for the month the photo Stream photos were imported
I have an iPhone too since this week and there are the Pictures or Photostreamfolders from my iPad without doing something.
I already called the apple support - they told me if i get the Lion OS X 10 and more than it would be okey
Since you have Mountain lion again this does not make sense
Maybe reading the set up instructions for Photo Stream - http://www.apple.com/icloud/setup/
and the FAQs - http://support.apple.com/kb/ht4486
Well, it´s not easy to explain this (especially in english) when you can´t see whats on my computer...I had a nice talk to 2 People from the Apple Support - and even they don´t know the problem (cause all settings are fine, cause i can read and work with instructions), but try to solve it the next few days.
But to let you know: I imported my pictures on my iPad while i was travelling for 5months and created already Photostreams there to share with my friends at home - but on my Mac they aren´t there in iPhoto or even worst - they are not in my iCloud. And i can´t open other Photostreams from friends with the link they sent to me. On my iPhone it´s working - without make other things, they just have been there (same to the iPad).
And the thing with the folder - i want to have my pics sorted by the places i was or create folders to share with friends, cause i can´t share over 5000 pics. So it´s my thing if i want folders - not yours!
