Jquery with rails 3

this jquery code works when referenced internally but when i place it in the application.js file. it dosen't work
working when referenced like this:

##application.html.erb
<script type="text/javascript">  
	$(function () {
		setInterval("rotateImages()", 2000);

	});

	function rotateImages () {
		var oCurPhoto = $("#slideshow div.current");
		var oNxtPhoto = oCurPhoto.next();
		if (oNxtPhoto.length == 0)
			oNxtPhoto = $("#slideshow div:first");

		oCurPhoto.removeClass('current').addClass('previous');
		oNxtPhoto.css({ opacity: 0.0 }).addClass('current').animate({ opacity:1.0 }, 1000, 
			function () {
				oCurPhoto.removeClass('previous');
			});	
	}


but not like this:

##application.html.erb
	<%= javascript_include_tag "application" %>
  <%= javascript_include_tag "jquery-1.4.3" %>
	<%= javascript_include_tag "rails" %>
  <%= csrf_meta_tag %>

##application.js
(function () {
	setInterval("rotateImages()", 2000);

});

function rotateImages () {
	var oCurPhoto = $("#slideshow div.current");
	var oNxtPhoto = oCurPhoto.next();
	if (oNxtPhoto.length == 0)
		oNxtPhoto = $("#slideshow div:first");

	oCurPhoto.removeClass('current').addClass('previous');
	oNxtPhoto.css({ opacity: 0.0 }).addClass('current').animate({ opacity:1.0 }, 1000, 
		function () {
			oCurPhoto.removeClass('previous');
		});	
}

I believe that's partially correct; but the standard Rails JS library (Prototype) also uses the $ tag, so I think you have to also tell jQuery to redefine the $ tag to something else, like this:
  jQuery.noConflict();
That will change the jQuery $ variable to jQuery

See http://api.jquery.com/jQuery.noConflict/ for more information.

Definitely as JESii said, you would need jQuery.noConflict() if you also include the Prototype library.

By default the Prototype library is included in the Javascript expansion :defaults, so you need this if have something like:

<%= javascript_include_tag :defaults %>

or:

<%= javascript_include_tag "prototype" %>

in your layout.
