I can't import JPEGs in iPhoto -- I get an error message that the file is not a recognized type. But the JPEG is perfectly fine -- it opens in Preview. Also I can import the JPEG into iPhoto when I login as another user on my computer.
So it would seem that something is wrong with my user account. What can I do?

What are you trying to import them from, a digital camera or are they already on your hard drive?

The first thing I would have suggested was trying another user. If they work with iPhoto on another user then it might be a preferences or permissions problem. Try repairing the permissions through Disk Utility, it could be that something in your account got screwed up.

Have you tried draggin them into the Library as well as going through File>Import?
