.img file extension

recently i downloaded a movie with the file extension .img ... what sld i do in order to watch?

.img a clonecd cd image file (like .cue .bin .iso etc). isobuster should be able to open it.

i downloaded isobuster also.. but how to use it? can anyone teach me?

i tried opening the file with isobuster but it kept showing me error that cannot open the file.. y is this so?

jus rename it to .iso .img is just an iso by another name.
