Strange, I have no problems reading that image on my computer:

IDL> print,!version
{ alpha OSF unix 5.4.1 Jan 16 2001 64 64}
IDL> a=read_tiff('8bit.tif') & help,a
A BYTE = Array[379, 1200]

Is the fact that this is 379x1200 instead of 1200x379 part of the problem?

An interesting thing is that when I open this file in xv, I get the error
message

Warning, TIFF directory is missing
required "StripByteCounts" field, calculating
from image length.
