i resolved this as per below process

add image path to web.config file as like

after adding image path into web.config file ,include crystal report into your solution and in that crystal report add parameter field ,the filed name will be the same as like the key from web.config file,here i have parameter field as "logo"

fetch image into c# code onto the page to which you are binding report viewer as like bellow code

protected void Page_Load(object sender, EventArgs e)

{

string imagePath = ConfigurationManager.AppSettings["logo"].ToString();
