image1.visible=true not working

I am sending an email and it takes a few seconds to collect data, format it, verify it, and send it, so for user interaction I have placed a gif image of a progess bar for user to wait,.

I have made this image visible property to false in design mode, now i want to show this image when user clicks send email and hide it when image successfully sent. I have written email sending code and it works fine, and at top of that I wrote image1.visible=true and at bottom of email sending code I image1.visible=false and displayed email sent successfully in a label.

However, image is not displaying. Please help or any alternative?

I would recommended you to use UpdateProgress. here is the sample: 

<asp:UpdatePanel runat="server" ID="upchk1">
    <Triggers>
         <asp:AsyncPostBackTrigger ControlID="Button2" />
         //you can even specify button which is outside of UpdatePanel.
    </Triggers>
    <ContentTemplate>
       <asp:Button ID="Button2" runat="server" Text="Check!" OnClick="Button2_Click" />
       <asp:UpdateProgress ID="UpdateProgress2" runat="server" AssociatedUpdatePanelID="upchk1">
          <ProgressTemplate>
            <asp:Image ID="Image1" ImageUrl="Style/spinner.gif" runat="server" />&nbsp;Checking...
          </ProgressTemplate>
      </asp:UpdateProgress>
    </ContentTemplate>
 </asp:UpdatePanel>

so, UpdateProgress's image (Image1) only will be visible while completing the task.
