the very first time when you are getting the image from webcam at that time save the image url into session and later onwords retrieve the image from session
in this way even in postbacks your image will never be null
  void LoadImage ()
{
if(Session["ImageUrl"]!=null)
{
Image.ImageUrl= Session["ImageUrl"].ToString();
}
else
{
Image.ImageUrl= CapturedImageUrl;
Session["ImageUrl"]=CapturedImageUrl;
}
The other option is to use htmlLocal storage to save image in client machine and after that retrieved from there
// Store
localStorage.setItem("imagepath", setthepathhere);

// Retrieve
document.getElementById("vImage").src= localStorage.getItem("imagepath");
