jQuery and WordPress problems

I am going round in circles with this, very frustrating.

So, I am trying to implement several jQuery functions into my WordPress site. I don’t know much about jQuery, but have been able to use a couple of scripts in non-WP sites with no problems.

Here is my test page.

I have a nicely working “Email this” revealer (see bottom of the test page). No problems there.

However, I have so far been unable to get any other jQuery scripts to work — case in point being the slideviewer plugin which, in the test, seems to load fine but does not do anything! I have searched around and have tried the noconflict script to no avail. I simply cannot think what is wrong, given some jQuery clearly seems to be working. I cannot help but think it has to be something WP related.

Here is the pertinent code from my header.php file:

<script src="/wp/wp-content/themes/ia_4/js/jquery1.3.1.js" type="text/javascript"></script>
		<script src="/wp/wp-content/themes/ia_4/js/jqueryeasing.js" type="text/javascript"></script>
		<script src="/wp/wp-content/themes/ia_4/js/slideviewer.js" type="text/javascript"></script>
		<script src="/wp/wp-content/themes/ia_4/js/menuscript.js" type="text/javascript"></script>

<script type="text/javascript">
    <!--
    jQuery(window).bind("load", function() {
    jQuery("div#gallone").slideView({
        easeFunc: "easeOutBounce",
        easeTime: 500
    });
});
//-->
    </script>
    <script>
    jQuery(function () {
        jQuery(".email_someone").click(function () {
            jQuery("#email_form").slideToggle(500);
            return false;
        });
    });
    //-->
    </script>

Does anyone have any ideas?

Thanks in advance…!
