Defer images combined

[Nophelet]

If you are using loading images from type "img src=" and the background images on your site, what should you do:
- Use  image code editing that loads with "img sec=" as described in the article here
- Use image code editing that loads with background images as described in the article here
- Remove a script if you have already used one or the other method
- Place only this script

<script>
function init() {
var imgDefer = document.getElementsByTagName('img');
for (var i=0; i<imgDefer.length; i++) {
if(imgDefer[i].getAttribute('dota-src')) {
imgDefer[i].setAttribute('src',imgDefer[i].getAttribute('dota-src'));
} }
$(function(){
$('[data-bg]').each(function(){
var bg = $(this).data('bg');
$(this).css('background-image','url(' + bg + ')');
});
});} 
window.onload = setTimeout(init, 600);
</script>

Now all your images will be loaded  "onload"
