Maybe you should think about who your talking to and where.
Anway, image grabber, and really the whole debug setup are going to take you more than a day to learn, if you have a deadline maybe setting up the xdk isn't the way to go. If this is the case, try to find another way to write your review. True, a review isn't as much without the pictures, but find some generic pictures on the internet that you might be able to use (royalty free, no copyright etc).
If your still hip to the thought of using the xig, do a little more research on how to setup the xdk bios and dash. And certainly, if you are too lazy or whatever to do this, your definately asking in the wrong forum.
If you really just want the answer handed to you without any work, you should at least try asking somone who knows - maybe in the
Development forum.
(also i don't know if xig will work with retail games - maybe find this out before u come to a dead end after learning about it all)
anyway, have fun, and i hope you learn something and later you can help somone else who is asking for the all the answers instead of wanting to research it themselves.
