How Do I Make A Ima File From An Iso Using Winimag

[aspenjim]

I have acquired a winpe w/ acronis utilities iso made by the master. I want to upgrade the acronis trueimage boot image to vs. 7. I have made an iso from the new acronis bootdisk. I have verified the iso file is bootable using MS virtual pc. How do I convert the iso into an *.ima file to replace the older one?

thanks,

aj

ps - these winpe utility disks are very cool. I've been working with a home-made custom one I started from BartsPE site, but can really appreciate the professional quality of the masters.

Also why are some of the extensions ima and others img? (i see the img files are a standard floppy size 1.44 and 2.88)
