Xfire's screenshot system allows you to take screenshots of your games, store and manage the shots locally on your machine, and quickly upload them to show off on your profile page. Each user is given 15 MB of storage space on their profile for screenshots, and old screenshots are automatically rotated out when you upload newer ones. You can add comments, lock your favorites to show off forever, and share your best shots with your friends anywhere on the web.
Xfire In-Game must be enabled to take screenshots. The default keys to take a screenshot are Scroll Lock + S, but you can choose a custom key binding by going to Tools -> Options in the Xfire client and selecting the "Chat" tab. We recommend a key combination that you can then bind to an unused mouse key with your mouse software.
