I’ve previously discussed a few services for sharing photos and files and how to take screenshots. CloudApp is a neat, free app I’ve discovered that not only makes it easy to share files, but even easier to share images of your screen.
Once you install it, make sure the “Autoupload Screenshots” option is checked in the menu. When you capture a new screenshot, Cloudapp will upload it automatically to their website, and the link to the image will be copied to your clipboard so you can paste it into an email or chat window.
