After downloading a site with multiple jpgs, trying to open the pictures
results in failure.  What I have found is that HTTrack has changed the header
information, and restoring a general jpg header resolves the problem.  The
question is twofold.

1.  Does anyone have a batch remedy for restoring the headers?  It is not in
my best interests to manually edit several thousand files.

2.  What steps must be taken to prevent this in the future?
It may be a site specific issue, since using the same settings on an alternate
site yielded no problems.

Thanks,
