Do you love taking tons of screenshots in your PC games? You may be interested to know that the latest Steam client beta is now able to take screenshots and save them into the Steam cloud. The best part here is you can save one gigabyte's (1GB) worth of screenshots for free.
After downloading the beta (opt into it through Steam's Settings panel), you can start taking screenshots and post them to your Steam community page along with a brief comment; non-Steam games are supported so add whatever you want with Steam's "Add a Game" feature. Since this is a beta, you may encounter problems so don't get this beta if you're not sure how to make Steam roll back to a stable release.
