First of all thanks for WinHTTrack! I only discovered it today, but it has
already proven very helpful.

Now, I'm trying to download images from a site that's structured like this:

<http://domain.com/folder/1>
<http://domain.com/folder/2>
<http://domain.com/folder/3>
<http://domain.com/folder/>... (up until)
<http://domain.com/folder/30000>

These numbered pages (without extension) are not linked anywhere. How do I
tell WinHTTrack to download the images from all these pages?
