Skitch, arguably the best free screenshot capturing service for the Mac, has relaunched with a new emphasis on sharing images with friends and admirers. In addition to quick screengrabs, resizing, mark-up and upload, the service now includes a lightbox view, subscriptions, comments and is now ad-supported.
Co-founder Cris Pearson says a web uploader and a Windows version will be available soon. His shots are here on Skitch and he recommends following other users including designers Wolfgang Bartelme and Chris Messina.
Skitch is quick, easy and free. It's also capable of more than you might think, including a variety of fonts and FTP options.
If you're looking to pay for something more heavy-duty on the Mac, TechSmith announced this week that its well-known Windows product Snaggit is now available for Mac as well.
