Javascript preloader 和 load(） 命令的错误

我正在编写一些按钮的脚本，其onclick命令加载外部html文件并更改图像的src。但是，在浏览器中打开.html文件时，我遇到了我所有的JavaScript代码，以纯简ASCII显示，显然未执行！:(

编辑 修复了"脚本类型"命令的问题。现在，脚本本身似乎根本没有执行。关于可能出现的问题的任何建议？

代码如下：

<script='javascript'>

现在是 HTML。

<div>
    <p style="text-align: center;"><img name="midimg" width="233" height="350"  class="art-lightbox" src="images/Fotolia_5170186_X-01.jpg"><br></p>

我做错了什么？
