Windows/Mac OS X only: Free screenshot and screencast sharing application Jing—which we first mentioned a year ago—turned one this week, and to celebrate they've significantly upgraded their free storage and transfer offerings. You now get up to 2GB of screenshot and screencast storage and 2GB of transfer per month on Screencast.com, which is 10 times the space and double the bandwidth. I'm a huge fan of Jing as the easiest cross-platform tool I've used to quickly share screenshots or screencasts (it's great for offering quick tech support). Anything you make with Jing can automatically be saved to Screencast.com, a local folder or network drive, an FTP server, or even Flickr (new since we first covered it) for quick sharing. Jing is freeware, Windows and Mac OS X only.
