UPDATE (June 30th, 2007)
I took my laptop into the Apple Specialist Store I got it from. After about and hour of trying to figure the problem out, we found out it was something in the photos. I had to open the photo in Photoshop, copy it, and paste it into a new Photoshop document. Was kind of a pain but it worked! (I think maybe it was a filter the photographer used on the black and whites.)
Screen Shot of black and whites properly imported at the bottom
I don't know what the deal is and I have never had this problem before, but now when I try to import photos into iPhoto...some of them don't import correctly. I end up with just a black thumbnail and an inverted looking full size photo when I click on it to view the whole thing. Any suggestions? Seems to be mostly the black and whites that are doing it. I am using iPhoto Version 6.0.6

EDIT:
You can see the black thumbnails and the distortion on the photos when selected in the screen shots.
