A test to see if the HTML5 canvas element draws part of a big spritesheet on various devices. So far, it's worked for me on Chrome and Firefox, on both desktop, and Android. No luck on iOS.

spritesheetTest.html

<canvas id='test' width='400' height='400'></canvas>

<script>
  var img = new Image();
  img.src = 'http://fc01.deviantart.net/fs70/f/2012/187/b/b/ben_10__my_sprite_sheet_by_pyroman16-d56744g.png';
  
  var ctx = document.getElementById('test').getContext('2d');
  img.onload = function() {
    ctx.drawImage(img, 0, 0, 300, 300, 0, 0, 300, 300);
  };​
</script>
