    I think you should be able to extract some .img files using dd.

    I don't really know if it will work, as I've never tried it.

    The flashwizard pro people might use some kind of proprietary format, too.

    You can use the dd command to extract image files to a device, such as:

    Code:
    dd if=file_name.img of=/dev/sda1
    ...if you wanted to extract the image to a USB flash drive, for instance.

    I'm not sure what would happen if you tried to extract it to a folder in your /home directory, so be careful if you should try it. You can check the dd man page for dd for more information about using the command.

    Maybe someone that has more experience extracting img files will reply with more info.

    Fuseiso can mount many image formats: iso, nrg, mdf, img, bin...

    I also know of programs like nrg2iso, mdf2iso, ccd2iso, even b5i2iso. Unfortunately, I don't recall using img2iso, though it might exist. Most of these formats are <something else>+an iso block after that header. So, it *might* be possible to use dd to extract the iso from these image formats (maybe that's what these simple converters do as well) but it's not that simple as dd'ing the whole img. At least, you will need to know the starting position of the really useful data.
