Cannot find image saved to cloud from preview I wanted to post a cropped image on FaceBook.
I scanned the image into preview (import from scanner), cropped it and when "save in the cloud" was suggested I was quite happy to save it there.

Then I clicked image in FaceBook, clicked photos, but could not find the image anywhere. No Cloud folder and not in my stream. It is only available to preview as far as I can see.

Where can I find my image back when in an upload dialog?

PS: Today I wanted to upload a few flagged images from iPhoto, but they also did not show in the "Flagged images" in the upload dialog.

Any suggestions as to how to 

a) find images saved to the cloud from my iMac when uploading and
b) refresh the flagged folder in the upload dialog 

System: Latest Mountain Lion and iOS6.0.1 on all other devices
All iCloud documents get saved locally to ~/Library/Mobile Documents and preview has a folder there named com~apple~Preview with a Documents folder.

From Finder use Shift-Command-G to go to the folder

 ~/Library/Mobile Documents/com~apple~Preview/Documents


You can then copy or move the file elsewhere as needed.
