my rules:
-*
-/somesite.com/forum/viewtopic.php?f=*
-/somesite.com/forum/viewforum.php?f=*
+/somesite.com/*.jpg

This captures internal jpg on the domain.

But now I also check the include external non-html near links option.
But it is not getting imageshack images, for example.

Do I have to enable external link depth too?
And each time I change scan filters, somehow HTTrack is not using cache (very
slow mirroring), so it is very frustrating finding out if your new settings
work correctly.

And yes, I'm a newbie, but I did read the manual :)
