Repairing a damaged jpeg?

I have a few jpeg files that appear to have a corrupt bit-- the file is the full size it's supposed to be, but somewhere along the image, it stops abruptly (even during the middle of a line) and continues on as nothing but a field of gray. Anyone know of any utility that can salvage this?

Sometimes image files that won't open under one program will when using another i.e. some software is more "touchy" than others! If you can get them to open with some other imaging software then perhaps save them with another name or even in another file format before any final save as a jpeg.

If you don't have any other graphics/imaging software you could use one of those 30-day evaluations/trials. I've seen ThumbsPlus recommended for this job:

Or perhaps give the following page(s) a whirl:

I have noticed that some of these get messed up on downloading, especially if they were downloaded from a newsgroup. If they were posted in multiple parts (like Here is a pic of my car - mycar.jpg [1/2] and mycar.jpg [2/2],) both parts have to be downloaded and combined (or vice versa.) I have seen damaged pictures reposted by someone who originally messed up the download, or who got it from someone else who had messed it up.

You could try putting it together with winrar, but I don't see why someone would post something as small as a jpeg in two parts

These are images from my digital camera, not downloads. Most of them that are damaged I already had backed up on CD, but a couple-three hadn't been backed up yet. I can't see them completely in ACDSee, Paint Shop Pro, or Photoshop. Seems like I have a HD going bad-- all of the damaged images have been on one specific of the two drives.

Small hijack, but on usenet, posts are most always broken up into multiple parts, with the standard pretty much being 7500 to 10,000 lines. This is under the size of a medium sized jpeg around 150-200k. Most news reader programs will automatically seperate these parts when you post, and combine them when you download, although there are several ways someone could download the first part but not the second (pics will open even when they are corrupted, most other files won't.)

As far as the original post goes, it does sound like a hard drive problem now.
