A strange one this...
I've just upgraded from a G5 Powermac to a MacPro. In iphoto all my photos show up as thumbnails, but when I try and double click on them, at least half come up with a black (or sometimes white) screen. It gets stranger still... If - having double clicked on a photo that then comes up as a black screen - I press info, it clearly is recognising the photo: it gives all the details, including file name, date, and it even recognises faces. There's just nothing to see. Furthermore, if I scroll backwards along the filmstrip and eventually find a photo that iphoto is prepared to display, I can then scroll forwards and several photos that were previously invisible suddenly become visible. But if I then try and edit them, then they go invisible again!
I've tried rebuilding the library, but that's made no difference at all.
Any ideas? I'm stumped...
Thanks in advance.

    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). 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?

    Thanks for this.
    Your options 1,2,4 and 5 all had no effect. So to option 3. I've used file/reveal in finder, and on the affected photos the option "modified file" is greyed out (leaving only "original file" as an option). Whereas on unaffected photos both options are available. Strangely it seems to be impossible to navigate to the iphotos photo library to check out what has happened to the modified photos, as when I choose HD/users/my name/pictures/iphoto library, there is no further option to find the folders with the photos in them. However, when I choose file/reveal in finder on an unaffected photo, the folder structure does show up, and using this method I can find no trace of the images that are not showing. But if the images have somehow been deleted, how come iphoto prompts me for "faces" when it comes to display a photo that isn't there? And how come is has all the exposure and other info (revealed when choosing info on the affected photos?
    Thanks

    Select one of the affected photos in the iPhoto Window and go file -> Revert to Original

    Does that help any?

    Nothing strange about this. Since iPhoto 7 (iLife 08) the old iPhoto Library Folder is a Package File. This is simply a folder that looks like a file in the Finder. The change was made to the format of the iPhoto library because many users were inadvertently corrupting their library by browsing through it with other software or making changes in it themselves.

    See below for details on accessing your files...

    And how come is has all the exposure and other info (revealed when choosing info on the affected photos?


    Because this data is added to the database when you import a photo.

    There are many, many ways to access your files in iPhoto:

    You can use any Open / Attach / Browse dialogue. On the left there's a Media heading, your pics can be accessed there. Command-Click for selecting multiple pics.

    Open dialogue
    Uploaded with plasq's Skitch!


    *_(Note the above illustration is not a Finder Window. It's the dialogue you get when you go File -> Open)_*


    You can access the Library from the New Message Window in Mail:

    New Message Window
    Uploaded with plasq's Skitch!


    There's a similar option in Outlook and many, many other apps.

    If you use Apple's Mail, Entourage, AOL or Eudora you can email from within iPhoto.

    If you use a Cocoa-based Browser such as Safari, you can drag the pics from the iPhoto Window to the Attach window in the browser.

    *If you want to access the files with iPhoto not running*:

    For users of 10.6 and later:
    You can download a free Services component from MacOSXAutomation which will give you access to the iPhoto Library from your Services Menu. Using the Services Preference Pane you can even create a keyboard shortcut for it.

    For Users of 10.4 and 10.5
    Create a Media Browser using Automator (takes about 10 seconds) or use this free utility Karelia iMedia Browser

    Other options include:

    1. *Drag and Drop*: Drag a photo from the iPhoto Window to the desktop, there iPhoto will make a full-sized copy of the pic.

    2. *File -> Export*: Select the files in the iPhoto Window and go File -> Export. The dialogue will give you various options, including altering the format, naming the files and changing the size. Again, producing a copy.

    3.*Show File*:

    a. On iPhoto 09 and earlier: Right- (or Control-) Click on a pic and in the resulting dialogue choose 'Show File'. A Finder window will pop open with the file already selected.

    3.b. On iPhoto 11 and later: Select one of the affected photos in the iPhoto Window and go File -> Reveal in Finder -> Original. A Finder window will pop open with the file already selected.

    Still not solved.
    The "photo/revert to original" option is greyed out on the affected photos.
    If I try and email one of the affected photos it fails to attach and a finder message pops up saying: "MS Entourage got an error: Can't make some data into the expected type".
    If I drag and drop an affected photo onto the desktop it makes a copy perfectly well
    When I use the Open command in Safari to navigate to the affected photos, there is a "reveal in finder" option, but this takes me to the original jpeg, not the iphoto library. However, for photos that are unaffected, there is no "reveal in finder" option!
    When I use the MacOSXautomator services option, it simply opens a pane showing all the iphoto images, it doesn't actually open a folder with a folder structure. Again, the "reveal in finder" option only takes me to the original jpeg, not the copy made for iphoto. Unaffected photos do not have a "reveal in finder" option.
    So I'm still flummoxed!
