    In my imagination
    I would try converting them to another image format so OSX can generate new previews.

    Do you have Photoshop or some other image editor? I am not too familiar with iPhoto, so I don't know if it can convert JPGs to TIFFs or anything.

    Look for the commonality in the corrupted images by opening several good and bad images in Bridge and check the metadata. That's a start in finding a possible solution.

    Hold down Control + Option + Command, then press 8. That'll set ya straight. :D

    Seriously though, I hope the transition to your new Mac goes smoother than it has so far.

    Sounds to me like a "color space" issue.

    What happens is that on the PC the software is completely ignoring the color profile and assumes it is just sRGB. But then inside the file there is a profile much different from sRGB. the Mac does the "right thing" and actually reads this information but of course the Mac is not smart enough to know it is corrupted.

    If I'm right you can fix this in Photoshop by assigning an sRGB color space with would force the internal information in the JPG fie to match what those non-color managed applications assume.

    BTW I went to look at your file and it's not there. So I'm guessing.

    it inverts the colours on your screen. you do the key combo again and it goes back. I find it handy when some websites use white text on a black background.

    unfortunately I can't help with your other problem. :eek:

    can you post one of the offending images here as it is before you put it in iphoto? I'm betting somehow you've converted them to CMYK or LAB.

    Sometimes OS X freaks out about windows CMYK jpgs. I don't know how you would have gotten them that way to begin with, but that's irrelevant now.
