Thank you very much for your reply.

I was trying to view these files on Windows using irfanview and 
photoshop, and photoshop did complain about unsupported compression 
method. You are right on target.

Being, hmm.. , a perfectionist , I wonder - is there any way to set up 
Hylafax to convert from JBIG to normal TIFF format ( no compression ).

Any response will be greatly appreciated.

Little be more info on a problem , while receiving JBIG compressed 
images on email from Hylafax I had this strange message


Does not look like a facsimile?
ReceivedOn: ttyS7
    CommID: c000000289


would this be caused by the JBIG compression?

Regard

Anton
