We just released an extension for Google Chrome that allows you to do screen capture right in your browser! This will currently work for people using the latest development build of Chrome (4.0+) (and will work for everyone else once Google releases the beta version of Chrome, with extensions support).
You can download it here.
The extension adds an icon to Chrome that allows you take a screen capture of the visible portion of any webpage and open it instantly in Aviary's visual markup editor (Falcon) where you can crop it and add arrows and notes. You can also change the default editor if you'd prefer to open it in our other apps (like our advanced image editor or color editor).
Once you have a screenshot you can easily download it to your desktop or if you have an Aviary account, save and host it online at Aviary. You can easily push the screenshot to Twitter, Facebook and other locations too.
The extension also lets you quick launch any of your favorite Aviary editors.
There are some limitations because this is an early release and Chrome doesn't allow some functionality just yet. One limitation is that we can't capture the full page (that is normally hidden until you scroll down) and we can't capture Flash content. Both of these things are available in our Firefox addon for screen capture. We expect that in future releases these options will be supported.
Here's a quick video showing it in action:
PS. Happy Thanksgiving! Please remember to thank the turkey for being so delicious.
