Hem. This is not the most frequent use of httrack, but, 
anyway.

Generally, the "Options"/"Scan rules" allow you to control 
precisely what you want to download. You may specify things 
like:

-* +www.yoursite.com/yourdirectory/yourscript.shtml* +*.jpg 
+*.gif

To grab only what you want. Remember that html pages has to 
be captured to get links, and then images inside them.
