How to insert page loading code on my aspx page?
<p>I prepared a ASP.NET web site. But it contains lots of flash controls. When you enter the page, some flash controls can't load but page is opening.So flash parts are shown not well.</p>

<p>To solve this problem, I want to add a page loading code on the aspx page.An image or a gift is illustreted until the page fully loaded.</p>

<p>Please, give me a code  but I can't know how I add the code to aspx page, so I need some instructions as well.</p>
