problem with TIF on windows

[Jacob Delfos]

Jiri,

Your TIFF uses a JPEG compression internally. TIFF files can use quite a 
few different kind of compressions. It seems your TIFF file is not 
healthy. Is there any particular reason why you do not want to use a 
JPG, since your file seems unhealthy, and since JPG works? If it already 
uses a JPG compression internally anyway, converting it to JPEG will not 
be a major drama in loss of quality.

You could use a simple program like Irfanview (www.irfanview.com; easy 
to use) to convert it to another format, or even to .tif format 
(choosing your preferred compression). Make sure to keep the .tfw file 
(best rename to .wld file for jpeg), and don't resize your image.

regards,

Jacob
