A modulable version with JQuery, add this at the end of your file:
<script>
$(function() {
$('img[data-src-error]').error(function() {
var o = $(this);
var errorSrc = o.attr('data-src-error');
if (o.attr('src') != errorSrc) {
o.attr('src', errorSrc);
}
});
});
</script>
and on your img
tag:
<img src="..." data-src-error="..." />
