Anyone know how to fix an "empty" JPEG file?

[Guest]

I'm fairly new to photo editing but I've been working on some photos recently that I started editing in iPhoto '09, and eight of the photos need a text caption added to them. I tried to export them to Photoshop to do this (iPhoto doesn't seem to be able to do that) and five of the photos opened perfectly. Three, however, would not open at all; Photoshop said it "could not complete your request because a JPEG marker segment length is too short (the file may be truncated or incomplete)." And when I try to open it in Preview, it says the file is "empty." This is clearly not the case because I can see the edited photos just fine in iPhoto, I just can't open it in any other application. All the photos are from the same camera and were taken and uploaded on the same day to the same program. I really have no clue how to fix this or why it happened; I guess I could just reimport the photos straight from the camera but it would lose all the edits I did so I'd like to avoid that. If anyone knows what to do to fix this, please answer asap! Thanks!

Either the file is corrupt, or it is not a JPEG file and simply has the wrong file extension on it.

Try this application, http://www.lemkesoft.com/download.html  - Graphic Converter, and see if you can open it in there.
