Urgent! how to add the animation in update progress

coould any one tell me how to add the aninmation in update progress...this will help me alot...

<asp:UpdateProgress ID="UpdateProgress1" runat="server">
<ProgressTemplate>

<div style="margin-top:60px;">
Update is in Progress.....
</div>
</div>

</ProgressTemplate>
</asp:UpdateProgress>

You can display gif image, in a similar way as you display text e.g.

<div style="margin-top:60px;">
<img id="updateInProgressImage" src="http://pics.10026.com/?src=" alt="Update in Progress" runat="server" /> please wait...
</div>

Thanks for the reply...i have 1 question:

should i put image path in "src" or in "id"? i kept in src and it worked in IE but it won't show on firefox??

also, how can i control the font-size of the "please wait..."?
