Reload images on failure every x seconds
// Reload images on failure every x seconds
$("img").error(function() {
var path = $(this).data('src');
var img = $(this);
// Put back mock image
$(img).attr('src', '');
// Increment loading counter
var attempt = ($(img).data('attempt') || 0);
$(img).data('attempt', attempt);
// Get reload time in seconds with exponential backoff (between 1 and 120 seconds)
var time = Math.min(120, Math.round(Math.exp(attempt/5)));
// Reschedule a loading attempt
setTimeout(function() {
$(img).attr('src', path);
}, time*1000);
