hy everyone!

My problem is simple: I want to download images on the forum 
<http://www.mechmate.com/forums> httrack with a purpose of private consultation
because my connection does not allow me to see it just as often as I want ...
: (

The site is well copied. But the images are not downloaded.
Going on the properties of images of the site I find a complicated addresses
like this:
<http://www.mechmate.com/forums/attachment.php?attachmentid=5110&stc=1&d=1246438417>

AS you see in http  address, the image is designated by     
attachment.php?attachmentid = 5110 & stc = 1 & d = 1246438417    ... it is
clearly not located in a file nor designated as jpg image ... : (This is 
Chinese language  for me!

 I do not know how to get them.
If you can help me it would be great!
sorry for my bad english ;)
