I have been using HHTrack for about a year backing up a site from another
server.  I run it as a cron job once a week.  

Recently an issue has started where the copy of the site is missing many JPGs. 
I have manually run the command and see the JPGs I need
(sub-terranean.html.tmp and bollards.jpg.tmp) while HTTrack is still running.

When HTTrack finishes the temporary file (bollards.jpg.tmp
 in this example) is gone and the is no bollards.jpg file either.  The HTML
files are saved

How can I prevent deleting of the .tmp files that I need?  Some of the JPGs
that I need are referenced in .CSS files.  I have seen other posts in the
forums that refer to CSS and similair issues but none sole my problem.

command line:
/usr/local/bin/httrack -A100000 mydomain.com
