$('document').ready(function () {
var animateGif = function () {
if ($(this).children('img.post-image').attr('src') != '/static/spoiler.png')
$(this).children('img.post-image').attr('src', $(this).attr('href'));
}
$('div.file').children('a[href*=".gif"]').each(animateGif);
$(document).on('new_post', function (e, post) {
$(post).find('div.file').children('a[href*=".gif"]').each(animateGif);
