white icon/missing photo puzzle... photostream?
Here's a weird puzzle maybe one of you iPhoto experts can solve:
I'm using the most updated versions of OS X and iPhoto, and up until recently have had no trouble.
However...
I was scanning through my full photos database the other day and spotted over 700 white icons where photos should be. Clicking on each goes only to a black screen in the edit area. Under the "File" menu, searching for the original says the file cannot be found. And yet searching for the file name in Finder reveals itin the iPhoto library.
Now add this wrinkle...
If I hold down the command key and click the file in Spotlight, I get a spinning wheel and iPhoto freezes up. If I double click the Finder version of the file, it opens in Preview. However, if I drag the Finder version of the file back onto the iPhoto icon, iPhoto says it can't import the file because it's unreadable.
Note that the file we're talking about is and image and is a JPG.
One more thing...
I've just discovered that all the problematic image files may be ones that I've selected for various Photostream albums (there are too many for me to check, image by image, but it's been the case of all those I've checked so far). Strangely, I can find the original versions okay in older year-sensitive smart folders inside of iPhoto.It's just that they reappear in my more recent list of iPhoto photos as well, as the white icons.
Follow all that?
And if yes, is there a fix?
To note, I have already tried all of the rebuild options built into iPhoto with no luck.
It's a real puzzler... I just want to make sure I'm not losing any photos here.
