## just some ways to check if a url exists

# method 1 - from Simone Carletti
require "net/http"
url = URI.parse("http://www.google.com/")
req = Net::HTTP.new(url.host, url.port)
res = req.request_head(url.path)

# method 2 - from some kid on the internet
require 'open-uri'

// this is a rudimentary attempt to implement a slideshow that doesn't saturate downloads with every image upon page load; instead the first slide is embedded in the HTML and loads with the page immediately, the second upon DOM ready, and subsequent upon the advance of each slide; additionally a progress indicator is displayed and slideshow paused if the next slide is still downloading thus preventing displaying partially downloaded images, or missing images entirely

var slides = [ // this is an array of the html representing each slide to display, in reverse order starting with the second slide (the first should be in the HTML page, see below); this markup may contain anything (e.g. li, div, captions) and should have corresponding css, but the first img tag is assumed to be the main image which we monitor for its download state
    '<img src="/path/to/file4.jpg">',
    '<img src="/path/to/file3.jpg">',
    '<img src="/path/to/file2.jpg">',
];

// callback functions
function loadedSlide(){
