ISO images are expected to contain the binary image of an optical media file system (usually ISO 9660 and its extensions or UDF), including the data in its files in binary format, copied exactly as they were stored on the disc. The data inside the ISO ima IS...
.img is generally for USB installs[1], .iso is usually for CD/DVD burning (installs).
