I googled on "mount v2i image" and there are plenty of hits to look at, eg:

It looks like your poster reference may be to Symantec's Backup Exec System Recovery tool. Please note that this forum is not for Norton Ghost support, but for Ghost Solution Suite, which is based on different technology. You will find a sticky posting at the top of this forum which has a link to the Norton Support Community, and they may be able to give you more salient advice.
I don't believe ImageX is an option as this is a tool intended to work with wim files, part of Microsoft's imaging solution. Perhaps you are thinking of VMware which is also able to mount a variety of image formats.
