As you probably know you should not run init functions before the DOM is fully loaded.

The reason you must run the init function as soon as the DOM is ready, is that once the page has loaded the user starts hitting buttons etc. You have to minimize the small inavoidable gap where the page is loaded and the init-functions haven't run yet. If this gap gets too big (ie. too long time) your user might experience inappropiate behaviour... (ie. your upload will not work).

Other users have provided fine examples of how to call the init function, so I will not repeat it here... ;)
