html - Print Screen to Website -

-

this question has answer here:

my user need screen shot error message throw website. should directly paste clipboard in website instead convert jpeg. preferable browser firefox. try use zeroclipboard works words not images. appreciated if advice , share links references.

simple answer: can't. there no web-standards way read binary data clipboard, not believe flash or silverlight either (flash can expose bitmap data clipboard, under air, i.e. not in browser context).

you write small desktop utility program users download , run, take screenshot , upload them, without users have paste image paint, save disk, , upload <input type="file">.
