For example when I want to download the following link

<http://www.hongfire.com/gallery/showgallery.php/cat/510>

The individual picture html/jpg pages don't get save as 
there are no *.xxx extension:

.../showphoto.php/photo/15274/sort/2/cat/510/page/1

It is not a hard problem to solve, and yet I can't figure 
out a way to get the page. Any idea?
