Answer 1

Image files are not pictures and as such they cannot be converted to pictures such as .jpg files.

.img refers to binary files with the .img filename extension that store raw disk images of floppy disks, hard drives, and optical discs or a bitmap image – .img. https://en.wikipedia.org/wiki/IMG_(file_format)

To be a little more specific, I believe you are referring to binary disk images, because you specified (.img disk image).

Also, the binary file you linked doesn't look like a bitmap. The linux file utility didn't recognize it and neither did imagemagick.
