The JPEG in question is displayed as a blob by Windows Image Preview but I can view it with XnView (www.xnview.com). $ tiffinfo -c -j -s test-original.tif TIFFReadDirectory: Warning, test-original.tif: wrong data type 4 for "JpegProc"; tag ignored. TIFFReadDirectory: Warning, Photometric tag value assumed incorrect, assuming da ta is YCbCr instead of RGB. OJPEGSubsamplingCorrect: Warning, Subsampling tag is not set, yet subsampling in side JPEG data [1,1] does not match default values [2,2]; assuming subsampling i nside JPEG data is correct.
