Easy way to upload a screenshot (from clipboard) through a browser form

i am pretty sure, that i've seen such a feature on a website somewhere in the web.

i want to give the user a form, where he can input some data and attach the current clipboard content (very likely a scr开发者_运维知识库eenshot) to the form and then submit it as an image file.

after all, i don't want the user to go through all the hassle: take a screenshot, open his favorite image processing app, paste the screenshot, save it as a file, then go to my form to click a browse button and eventually search for the saved file.

there has to be an easier method, with all the ajax-jquery-web2.0-stuff.

thanks in advance

Jira does this using a signed Java applet. I'd suspect if it were possible to due it in pure JavaScript, that Google Docs would have this feature, which it doesn't.

(I can't comment on Chris Beaman's answer, so I'm giving this as a standalone.)

Uploadscreenshot.com does do this, and they use a Java applet to do so. I don't think it's possible via any generic form element that I'm aware of.
