If you specified +*.gif +*.jpg (and other similar filters) 
in Options/Scan Rules, and these images aren't captured, 
this means that httrack did not detect them. There is 
nothing to do in such cases, except haking the html code 
using an editor :(

No, forms are not yet handled, mainly because
- they are hard to handle
- handling forms would cause an awful mess, due to the 
number of forums with unprotected "delete" or similar 
things..

Yes, and quite hard to configure (which post should be 
treated? what to fill by default in "input type=text" 
areas?)

maps?
Nope. The only way would be to simulate mouse clicks each 4 
or 8 pixels, in both XY axis, but this trick actually sucks 
so much that I refused to implement it :)
