Ubuntu mounts .IMG files as read-only?

[CommanderLiamTHX]

Don't ask why, but I need to put things in an IMG file in Ubuntu. If I use the built-in Archive Mounter to mount the IMG as a drive, it's read-only and I can't put anything in it. I've tried starting Nautilus as root with sudo su, but that still didn't work. Is there a way that I can make the file read-write?

You need to extract the contents of the .IMG file, make your changes, and then re-package into an image file.

That's exactly my problem. If I make an image file, I have to mount it as a disk to put the files in it. But when I drag files into it, it doesn't let me because it's read-only.
