Image file types

I dowloaded the image of a game that ended with .iso. What kind of file is this, and what program do i use to burn it?

oh...my.....God

1) Register with the forum

2) Use this handy little thing called SEARCH

3) Use an application that will burn ISOs, like Adaptec/Roxio Easy CD Creator
