img files are similar to iso files or disc images. img isn't a image file in the same sense that you are talking about. Are you sure you need it to be a .img extension?
Indeed, I rather doubt it, I haven't even heard or seen that file extension.
Facts are it actually have nothing to do with that, most cameras normally won't let you put pictures back onto them and then view them, however you can use it as a storage device but you won't be able to view them.
