Fishy... sure. But strictly speaking not invalid, and most readers
should be expected to survive. Remember that this is strips, and any
last strip is truncated (unlike is the case with tiles), so any value
RowsPerStrip value bigger then or equal to ImageLength just means it's a
single strip image and the single strip is ImageLength rows. You could
change it to 3356, and still it would be a perfectly valid file with no
other change required.

But, sure, it's fishy. If I was Irfan, I'd want to investigate
nonetheless.
