You can either wrap the img control within an <a href> control, set its ID, and change the href in the codebehind, or you can use the ImageButton control in ASP.NET and set its onclick and ImageURL properties.

If you are using Visual Studio, just open the code-behind .aspx.cs file and add code to the Page_Load event.  

MyImageButtonControl.ImageURL = "your image src goes here";

Then you have a few options.  If you want to post back when the button is clicked, you can handle the OnClick event of the button.  The easiest way to do that is to double-click on the control in designer view, and Visual Studio automatically adds the handler for the OnClick event.  Or you can manually add it:

void ImageButton_Click(object sender, ImageClickEventArgs e)
      {
         Response.Redirect("The url you want to send them to goes here");
      }

and make sure to wire it up to the control by adding the OnClick attribute to the <asp:ImageButton> tag

<asp:ImageButton id="imagebutton1" runat="server"
           AlternateText="ImageButton 1"
           ImageAlign="left"
           ImageUrl="images/pict.jpg"
           OnClick="ImageButton_Click"/>

OR if you don't want a postback to occur, you can use the OnClientClick event and use Javascript to handle the link.  In that case add this to the Page_Load event:

MyImageButtonControl.OnClientClick = "location.href='my url goes here';"
