When I relocated my Masters, there are some images that don't show the preview of the thumbnail. I don't understand why this is and I would like to correct it so that I can see the preview when browsing the images in the finder. I have tried consolidating the images into the Aperture Library and regenerating the previews and then relocating, etc, but have had no luck.

Any ideas on how I can get the images that don't show previews to show them instead of the generic JPEG Preview image?

Thanks,

    Hi Mac.

    The first thing I'd check is that you haven't specified something like "don't make Previews" for the Project(s). The [Previews page in the User Manual|http://documentation.apple.com/en/aperture/usermanual/index.html#chapter =6%26section=15%26tasks=true] is thorough -- read through it and see if anything jumps out at you.

    A couple of things you say, though, leave me confused.

    - What distinction are you making between "thumbnail" and "Preview"? +("there are some images that don't show the preview of the thumbnail")+ I'm pretty sure in Aperture 3 there are only Previews -- there are no thumbnails (or the Preview is the thumbnail).

    - Are you talking about the thumbnails in the OS X Finder? +("to correct it so that I can see the preview when browsing the images in the finder")+ The Finder decodes image files on its own. It does not -- to the best of my knowledge -- use any hitch-along files in Aperture.

    - What distinction are you making between Previews and "the generic JPEG Preview image"? +("how I can get the images that don't show previews to show them instead of the generic JPEG Preview image?")+ This I can't parse in any way -- sorry -- I may be having a day of thickness.

    First forget about the Aperture previews or settings. Seeing the file image in icon view in the finder has nothing to do with Aperture.

    Now is this happening that some folders show the image and some folders do not. Or is it happening in a folder where some images are shown and some (in the same folder) show the generic icon?

    If it's the first then check that you have *show icon preview* set in the view options for that folder.

    Any difference between the files that do show up and those that don't?

    Do they show up in the *Cover Flow* view? what about if you click *Get Info*? what about if you go into column mode does the preview show up then?

    Also what happens if you do a *Quick Preview* on the files.

    And again any similarity between ones that don't show up; differences from those that do? What type of files are we talking about? How many images in the folder? Internal or external drive?

    Come on help me out here I hate to go fishing

    You can try moving the finder preferences file to the desktop and re-launching Finder.

    In ~/Library/Preferences look for com.apple.finder.plist move that to the desktop. Then go to *Force Quit* select Finder and press Relaunch.

    If that doesn't do it, you might get better responses if you post to the *Mac OS X v10.6 Snow Leopard* forum. There is a subgroup for the Dock and Finder.

    If you find out anything post back. I'd be interested in hearing if there is a solution or if anyone has seen this before.

    good luck

    Mac -- in addition to Frank's excellent suggestions, you might as well try this:
    - Open the file in Preview and "Save As" JPG under a different name. Whatever anomaly is in these from-the-camera JPEGs might be excised.
