When you open some TIFF images, they appear black (faded and illegible)

Hi,

We use the ZetaFax software to receive faxes. Some of the faxes are
not viewable either in Microsoft Office Document Imaging or either in
Windows picture or fax viewer.

After some research, I had come across this image viewing software
that addresses this issue on their website and I downloaded the trail
issue and was able to view the .G3F (TIFF) image.

Is this a know issue that others are facing in Windows XP, or is there
any other way to view the TIFF image.

Any information would help.

Thanks in advance !!!
