  ctx.drawImage( img, 0, 0 );
};
var timer = setInterval( function(){
  if (imgNumber>lastImgNumber){
    clearInterval( timer );
  }else{
    img.src = "images/left_hnd_"+( imgNumber++ )+".png";
  }
}, 1000/15 ); //Draw at 15 frames per second

An alternative, if you only have 4 images, would be to create a single huge image with all four in a 'texture atlas', and then use setTimeout or setInterval to call drawImage() with different parameters to draw different subsets of the image to the canvas.
