Preview.app in Snow Leopard doesn't open some jpg files

Question

Preview.app in Snow Leopard doesn't open some jpg files.
Preview does't issue an error message, it behaves as I did't try to open file at all.
These images could be easy opened in iPhoto, so files seem to be OK.
I couldn't attach one such example image to this message, it's exceeds 2mb limit, but courtesy to google image could be downloaded by the link https://docs.google.com/leaf?id=0B56gs1tsb9aNYjA2MDdmNzUtOWY3NS00ODg1LWIzZDAtYTA 5YzFjZmZjYjRh&hl=en_US.
What's that? Should I file a bug?

Unfortunately, it sounds as if your internal disk failed (hardware failure).
Things to try:
(1) Boot from your Apple Hardware Test CD/DVD, which sometimes is a separate disk or sometimes is on the original OS install disk. Run the tests, all of them, to see what is amiss.
(2) Reset PRAM as described in  http://support.apple.com/kb/HT1379 . I don't think this is likely to help because even though your startup disk is not being selected, it seems that your internal disk is simply unable to be found or mounted, implying hardware failure more than software. But it's worth a try.
Probably time to take your computer in for repairs, either at the Apple Store or to an authorized Apple repair shop. Most likely they will simply replace your drive. You could also ask them to mount the old drive in an enclosure to see if files can be copied from it if you don't have a backup.
