I am using WinHTTrack Website Copier 3.33 (+swf).

I cannot find the right combination of options to copy a website with the
following types of links:

.../getfile.php?filename=f-j/flowers/morning_glories001.jpg

The thumbnails are saved but not the larger corresponding image.  It also
appears that the larger corresponding image is retrieved but not saved.  What
must I do to correct this situation?
Also, if I wish to avoid saving the thumbnails, how do I limit the retrieval
and saving of image files to those above a certain size (say, above 9K)?
