Steps for bulk downloading NASA Apollo images in the public domain.

apollo.js

// 0. open url: http://www.apolloarchive.com/apollo_gallery.html
// (n.b. all images to be downloaded are in the public domain)

// 1. install jquery by running this snippet in the console:

var s = document.createElement('script');
s.src = 'https://ajax.googleapis.com/ajax/libs/jquery/2.0.3/jquery.min.js';
(document.getElementsByTagName('head')[0] ||
    document.getElementsByTagName('body')[0]).appendChild(s);

// 2. click on an index page and run this to generate a list of image links:

var urlA = [];
$('a', frames.itemlist.document.getElementsByTagName('html')).each(function() {
    var ids = this.href.match(/disptn\('(\d+)','(.+)'\)/);
    if (ids) {
        urlA.push('http://www.apolloarchive.com/apg_thumbnail-test.php?ptr=' +
            ids[1] + "&imageID=" + ids[2]);
    }
});
var dl = window.setInterval(function() {
    if (!urlA.length) {
        window.clearInterval(dl);
        return;
    }
    $.get(urlA.pop()).done(function(d) {
        console.log($('table', d).find('a').last().get(0).href); // last url is best res
    });
}, 2000); // site-enforced rate limit

// 3. paste list of links into a file named images.txt and run:

// $ wget -i images.txt

// (you may need to install wget via `brew install wget` first;
// if you don't have homebrew installed, get it here: http://brew.sh/)
