Thanks for the reply. I am using httrack under Linux OS.

I tried with -r option.  If i specify -r1 then it doesn't crawl the images in
2end level subdirectory even that image is used by url.


So i tried with different combination. finally the below command has worked.

httrack 'url' -O 'folder' -q -Q -N 'test/%n.%t' -o0 -X0 -T30 -R1 -I0 -%F '' -F
'useragent' -B -S -n -r -* +*.jpg +*.jpeg +*.css +*.js +*.gif +*.bmp +*.tif*
+*.png +*.swf -*.exe -*.pdf -*.doc -*.zip
