How to get Screen Shot / Screen Capture from Web user on MVC site?

I've seen a few different apps that allow users开发者_开发问答 to take screen shots on their PC and then the utility will automatically upload the image to the web server. I'd like to incorporate this type of functionality into a new MVC site.

I could certainly just allow the user to upload their own image, but it'd be cleaner if they could click Capture Screen Shot and the image would be uploaded automatically.

My team is using ASP.NET MVC2 with a SQL back end database. We are certainly willing to look into 3rd party components (activeX based, etc.) that will allow us to achieve this.

update....

Google does something similar with their report a bug feature. So not unheard of...

The only way I've seen this work is through a java applet (it's how it's done in the youtrack application)

I managed to find an applet at sourceforge that at the least allow direct pasting of clipboard images... http://supa.sourceforge.net/
