File image won't show up

[merfman]

Hi everyone,

I recently borrowed a friends external hard drive to copy images from his vacation onto my computer, and on my computer (macbook pro) all the images I had on my computer before, and the vacation pictures don't have a preview image showing up anymore.

The file has a generic .jpg image and the file name underneath but no image of the picture itself.

I've went to Finder> View> Show View Options and made sure the Show Image Preview is checked, but the images wont show up.

Anyone know how to fix this?
thanks
