DECIMAL       HEXADECIMAL     DESCRIPTION
--------------------------------------------------------------------------------
37            0x25            TIFF image data, big-endian, offset of first image directory: 8
20756         0x5114          Copyright string: "Copyright Apple Inc., 2017"

file doesn’t know what it is, binwalk thinks it is a tiff, however gimp wont open it because:

Not a TIFF or MDI file, bad magic number 49091 (0xbfc3)

I belive your file is just corrupted, or at least in a really weird tiff variant that isn’t supported by the browser nor gimp.
