Exceptionally Uncaught

Like this picture? I did. I found it while looking around deviantArt the other week while looking for a new background image (well, actually a bigger version of it). Today I was cleaning up my desktop, and so moved the file somewhere more suitable. I like to use the thumbnail view for my picture folders, so I was a bit surprised by the thumbnail of the image:

I'm assuming this is the pre-photoshop version. My guess was that the thumbnail was generated before the photoshopping, but didn't get updated. Interestingly enough, when I reduced the original image size to post it here, the thumbnail still didn't change.
