 * `auto_fit`: set this to `false` to allow popups to be larger than the browser window. Default is `true`.
 
+* `auto_detect`: set to `true` to have QuickSlide attempt to automatically detect links to images, even ones without a `rel="quickslide"` attribute.  Only works for links whose URLs end in .jp[e]g, .png or .gif, and may have unintended side-effects, so use with caution. Default is `false`.

+* `no_wait`: set to `true` to initialise QuickSlide as soon as the browser has downloaded it. This is useful if if you are adding quickslide.js to your page after the DOM `onload` event has already fired (e.g. via insertion of a `<script>` tag). Default is `false`, meaning QuickSlide waits for the onload event before initialising.
