corrupt pictures, perfect thumbnails

[snappydragon]

I have a few jpegs that are corrupt. However, when viewing the
thumbnails, the pictures are ok. Is there a way of repairing the jpegs
to look like the thumbnails?

============================
How are they corrupt? Can you open the
files or do you receive an error? If you
receive an error...what is it?

Some of the files I cannot open. I am more concerned about the ones I
can open. For example, one image has a line running half way through
it, and the left side is discoloured (a darker blue) and appears to be
a zoom in on part of the original, if that makes sense.

No doubt...that is a corrupted file.

You might try a Google search for:
recover corrupted jpegs

Maybe you could find some software
that would help.

Good luck.

Thumbnails are, in general, a very low-resolution scaled version
of your jpegs when they were *not* corrupt. They contain far less
information then the originals (hence, thumbnails), and so are of
no use in recovering the originals.

Thumbnails often do not indicate the *current* state of a picture,
but only the state of the picture when the thumbnail was made.

Thanks for the info Michael. I'm not very adept at digital graphics,
and was not aware that was how thumbnails worked. I appreciate the
explanation. I guess I'll have to keep working with the originals.

I have several image files which have been reclaimed from a camera card.
I can see the thumnails, but they will not open in any of my imaging programs.
Does anyone know of a program which try to open corrupted jpg files?

Short answer: thumbnails mean nothing. Try an image "repair" utility
and be prepared for failure. ;-(
