It is not a good practice to load image in a webview.

The solution is to use some kind of image loader and the best one for your case is VOLLEY. It provides cache and image loading functionality better then any other image loader.

Here is the link.

You have to add file:/// before your image Path.

Did you try with something like 

// Exemple from asset folder
webview.loadUrl("file:///android_asset/mu_image.jpg");
 // From external storage
String base = Environment.getExternalStorageDirectory().getAbsolutePath().toString();
String imagePath = "file://"+ base + "/YOUR_FILE.jpg";
webview.loadUrl(base);

EDIT (after understanding the question ...)

You have to check if your web file exist 

public static boolean exists(String URLName){
try {
  HttpURLConnection.setFollowRedirects(false);
  // note : you may also need
  //        HttpURLConnection.setInstanceFollowRedirects(false)
  HttpURLConnection con =
     (HttpURLConnection) new URL(URLName).openConnection();
  con.setRequestMethod("HEAD");
  return (con.getResponseCode() == HttpURLConnection.HTTP_OK);
}
catch (Exception e) {
   e.printStackTrace();
   return false;
}
  }

Then 2 choices : - The file exists, show it - Or, show your default image

Source : Check if file exists on remote server using its URL
