For example, I want to download this page:
<http://hg101.classicgaming.gamespy.com/doa/doa4.htm>

I want to get all the images needed by the page (those within the img src=""
tag), but I don't want to get the linked images (those within the a href=""
tag).

For example, I want this image:
<http://hg101.classicgaming.gamespy.com/doa/doau-intro2a.jpg>

But not this one:
<http://hg101.classicgaming.gamespy.com/doa/doau-intro2.jpg>

Is it possible to do this with HTTrack?
