autoindex

example (refresh for different):

$(function() {
    var $wrap = $(".wrap");
    autoindex("http://i.johnweis.com/instagram/", function(e, imgs) {
        imgs.files.forEach(function(f) {
            $("<img />").attr('src', f.url).appendTo($wrap);
        });
    });
});

server-side

npm install autoindex then:

var autoindex = require('autoindex');

client-side

bower install autoindex or download the index.js file

autoindex works with or without jQuery. If you need legacy browser support, make sure to add jQuery to your page. To use autoindex, simply add it to your page via a <script> tag or use RequireJS.

NOTE: If you wish to use this in the browser, enable CORS on that site.
