Hello Suresh,

Please try in this way

HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(" http://IPaddress/FolderName/imageName.jpg");
request.Method = "HEAD";

bool exists;
try
{
request.GetResponse();
exists = true;
}
catch
{
exists = false;

HttpWebResponse response = null;
var request = (HttpWebRequest)WebRequest.Create("http://IPaddress/FolderName/imageName.jpg");
request.Method = "HEAD";

try
{
response = (HttpWebResponse)request.GetResponse();
}
catch (WebException ex)
{
/* A WebException will be thrown if the status of the response is not `200 OK` */
}
finally
{
// Don't forget to close your response.
if (response != null)
{
response.Close()
}
}
