image display based on condition in Vs 2005 asp.Net

I have used the below code to display image on top of the page. For condition1

div1.Visible = true;
div2.Visible = false开发者_如何学编程;

For condition2,

div1.Visible = false;
div2.Visible = true;

and the code in the aspx page is like this.

<div id="div1" runat="server" style="padding-left: 110px;">
  <img src="~/images/Package-Summary.gif" alt="Package Summary" />          
</div>

<div id="div2" runat="server" style="padding-left: 110px;">
  <img src="~/images/Process-Billing.gif" alt="Process Billing" />          
</div>

Here it doesnot show me the image, instead shows an error box in that part!! What might be the reason!!!

I think you need a relative path to the image:

<img src="../images/Process-Billing.gif" alt="Process Billing" />

Your images are using server-side paths, but they're not server-side controls. The divs surrounding them are server-side controls, which doesn't affect the images. Either convert the image controls to server-side or convert the paths to something the client can request (relative paths, ideally).

---

Actually your images are not picking the right path as you are using server path at client side. If you want to use root-relative path you should use server side Image control to assign path.

You can use an Image server control and can just change its source but I do not know what you exactly want. But on client you use relative path not root-relative path. For root-relative path you have to use server image control.

see the article

ASP.NET Web Project Paths

so it should be

<div id="div1" runat="server" style="padding-left: 110px;">
  <img src="../images/Package-Summary.gif" alt="Package Summary" />          
</div>

<div id="div2" runat="server" style="padding-left: 110px;">
  <img src="../images/Process-Billing.gif" alt="Process Billing" />          
</div>

or where ever your image directory is you can go back to your image directory by just adding another "../" before path to go back to image directory.
