Default Image Script

Specify Default Images for your <img> tags to be loaded when their images fail to load.

How to use

Simply place the script in default-src.js at the bottom of your page.

Raw
default-src.js
if (jQuery) {
$('img[default-src]').each(function () {
var $elem = $(this);
this.onerror = function () {
if ($elem.attr('src') != $elem.attr('default-src')) $elem.attr('src', $elem.attr('default-src'));
}
});
}

I think just a method would even do. Below is an untested code:

// default-src.js
(function($){
	$.defaultSrc = function() {
		$('img[default-src]').on('error', function(){
			if ($(this).attr('src') !== $(this).attr('default-src'))
				$(this).attr('src', $(this).attr('default-src'));
		}};
	};
})(jQuery);

Usage would be:

<script src="path/to/default-src.js"></script>
<script>
    $.defaultSrc();
</script>
