Why can't I load these tifs into Igor?

Some of the tifs, I try to load into Igor throw an error when being loaded saying "Unable to load the specified TIFF file". I've tried this both in code form and the interface for loading images under the data tab. I've attached the images that won't load below.


I can't load them into Igor, but then I can't open them in ImageJ either. What's the origin of the files? Are you sure they are TIFF?

christian.halaszovich is right. You can either change the extension to ".bmp" and just drag the files in to Igor to load them in the Pictures gallery, or you can use an ImageLoad command such as the following:

ImageLoad/T=bmp/Q "C:Users:username:Downloads:Img2.tif"
