This is a great idea. I was actually working on something similar yesterday! The beauty of this is that it has so many uses! I think all the haters need to chill and think about this for a minute. Yeah, it's probably a wrapper around webkit2png but outside of HN people...<p>1. Don't know how to use the terminal<p>2. Can't install webkit2png themselves (there are <i>a lot</i> of things that can go wrong - just ask me because they all went wrong for me yesterday. Everything from QT4 libs missing to $DISPLAY not being set, to the PIP package not installing correctly, to X-server connection problems)<p>3. Even if they had webkit2png they wouldn't know how to write a wrapper that took a damn screen shot, <i>then</i> resized it as a thumbnail, <i>and</i> changes the screen size so you can see a preview for multiple devices.<p>4. Don't have a Linux (or even POSIX compliant) machine locally or hosted somewhere.<p>This may seem simple here (well, to me it's more intermediate) but outside HN people will probably go nuts over this. Shameless sorta plug: I just started a project yesterday that does a very similar thing except it's meant for designers to take and store screenshots for inspiration and then plop them into a pretty UI/gallery. I'm going to open source it and host it though.
