Please check below working snippet.

  var imgsrc = ($(this).find("img"));
  return false;
function draw(image){
  var canvas = $('#c')[0];
  canvas.width = 800;
  canvas.height = 800;
  var c = canvas.getContext("2d");
  var img = new Image();
  img.src = image.attr("src");
  img.onload = function(){
    c.drawImage(img, 0, 0);
