I removed the MIME types and selected the option Use Old 
HTTP 1.0 requests, but the images are corrupted with htm 
extension.
The aspx site is send several tipes of files (HTM, gif, 
etc) but the HTTrack do not acept this. All the files are 
saved as htm files with some error in Header.

I used a file compare prog: some time were the char could 
be 0 he is saved as 20 (hex). Maybe binary files received 
as text files?The link has a reference to mime type:
image.aspx?id=1&MIME=image/gif
The httrack can see that?
Please, I need some help!

Thanks
