"Missing ImageLength filed" problem when requesting Tiff via MapServer

Hi,

I am trying to serve image via map server WMS. JPG, GIF, PNG all work well. But
when I try "fomat=image/tiff", it does allow me to download and save the image,
but I just can not open it. With GDAL gdalinfo to check the tiff image, it tells
me following info.

Error 1: MissingRequired: d:\temp\mapserv.tif: TIFF directory is missing
requried "ImageLength" field
GDALOpen failed -1

Anyone has any idea about thisproblem?

Thanks a lot

Henry
