Your TIFF file is perfectly legal. It has ImageWidth=180, ImageLength=145 and StripByteCounts=3335. It is easy to calculate:

tiffdump says:

RowsPerStrip (278) SHORT (3) 1<356>

356 rows per strip, when image length is 145? That seems a bit

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.
