I copied 214 pictures that I scanned on computer 1 to a thumb drive. Downloaded that to computer 2 and then imported those pictures into iphoto. All the pictures look normal in the folder I copied to computer 2 but in iphoto 76 are black. When I double click on them in iphoto they open fine but the thummbnails remain black. On computer 1 they are visable in iphoto.
On the second try I copied the pictures to a SDHC card and copied them to computer 2 and then installed them to iphoto with the same results.

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 rebuild the thumbnails. It can take 3 or 4 goes for this to work

Was the flash drive formatted FAT 32 or 64? That format handles image data, thumbnails for one, a little different than OS X so the thumbnails may have been lost when transferring. You can prove my theory wrong (or right) by reformatting the flash drive to OS X and try transferring those photos again.
