To get started, all you need to do is type in “aviary.com/” in front of the URL of the page you’d like to screenshot. From there, Aviary opens up its web-based image editor, where you can do things like crop, resize, and adjust the quality of the image, as well as use some of Aviary’s editing tools, like adding text, doodles, or arrows.
For easier use, this also comes with a bookmarklet which if clicked, it creates a screenshot of the page you're currently on and then takes you to the web-based image editor. To use the bookmarklet, simply drag this to your bookmarks toolbar: Screen Capture.
Once you’re satisfied with the image, all you need to do is either save it your desktop or save it online. From there, you can share it on the social sites of your choice, or do as us bloggers do and embed it in your blog posts.
This launch follows the release of Aviary’s Firefox plugin, Talon, which does essentially the same thing, but requires both Firefox and an install.
