Chrome: Hailing from the camp of literally-named-extensions, Explain And Send Screenshots is a screen capture and annotation tool for snagging and sharing screenshots right in Google Chrome.
Explain And Send Screenshots (EASS) makes it easy to snap a picture of the web page you're looking at, annotate it and share it immediately. You can either annotate the image directly in EASS with arrows, underlining, circles and text, or you can kick the image over to the online editor at Pixlr.
After you finish editing the image in EASS, clicking the "Done" button gives you four options for sharing your image. You can cut and paste the Pict.com link — images are shared through Pict — paste a pre-formatted HTML image link, download the image to save on your computer, or share the image on Facebook or Twitter. Explain And Send Screenshots is free and works wherever Google Chrome does. Have a favourite in-browser or portable screenshot tool? Let's hear about it in the comments.
