title: How to upload image into HTML5 canvas
body: <p>I am currently using <a href="http://paperjs.org" rel="noreferrer">http://paperjs.org</a> to create an HTML5 canvas drawing app. I want to let users upload images into the canvas. I know I need to make a login and signup but is there an easier way? I have seen the HTML5 drag and drop upload.</p>
