This is an issue with some Nikon cameras and some iPhoto installations on 10.6. There is no known resolution at this time.
iPhoto menu -> Provide iPhoto Feedback and report the bug
You can try re-install your system software.

Right and thanks, Larry!
I will reinstall my system software. Beyond that, my work depends on editing images... Just buy a different brand of camera??? Do others have this issue too?
What do you recommend? I appreciate your input.

No idea - there is no known resolution at this time - hopefully there will be - it might be OS, it might be iPhoto or it might be Nikon firmware - no idea
I would certainly report the porblem to both Apple and Nikon

I've yet to see a report of the issue on later versions of the OS. As I believe the issue is with 10.6, and that have been superseded twice now, I would not expect any further updates to it.
I am running 10.7.5 and I still have this problem. It has occurred on pictures imported from Sony, Nikon and Fuji cameras and always happens when a photo is edited in iPhoto.
I cannot believe that this problem can't be fixed.
My lastest uploads that turned black is when a photo was flipped, then edited, although it seems like it happens only 90% of the time.
YOU SHOULD NOT edit in iPhoto, or at leaset you should experiement after editing a photo by flipping back and forth through the edited photos to be sure the photo doesn't go black.

Do the resulting files also end up at 0 kb? If not, then it's not the same issue.
There are several possible causes for the Black Screen issue
1. Permissions in the Library: Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Include the option to check and repair permissions.
2. Minor Database corruption: Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild.
3. A Damaged Photo: Select one of the affected photos in the iPhoto Window and right click on it. From the resulting menu select 'Show File (or 'Show Original File' if that's available). (On iPhoto 11 this option is under the File -> Reveal in Finder.) Will the file open in Preview? If not then the file is damaged. Time to restore from your back up.
4. A corrupted iPhoto Cache: Trash the com.apple.iPhoto folder from HD/Users/Your Name/Library/ Caches...
5. A corrupted preference file: Trash the com.apple.iPhoto.plist file from the HD/Users/ Your Name / library / preferences folder. (Remember you'll need to reset your User options afterwards. These include minor settings like the window colour and so on. Note: If you've moved your library you'll need to point iPhoto at it again.)
If none of these help:
As a Test:
Hold down the option (or alt) key key and launch iPhoto. From the resulting menu select 'Create Library'
Import a few pics into this new, blank library. Is the Problem repeated there?

All new imported files do show 0 kb unless I revert them back to original file.
I can open the images in Preview after returning them to original file.
The problem only occurs with images from my Nikon, not my ten year old camera.
I have tested this by creating a new iPhoto library and the problem is repeated with all newly imported images from my Nikon only.
This is not an isolated image or two... I have done dozens of new imports and have the same problem. By the way, another curiosity is that no icon appears on the desktop for the new device (camera) so I have to just pull the plug every time... can't eject. Is this related?
