can you give the details?

You get the images on a remote (i.e. http://localhost:8080/image.gif)?

Sayon ra, gamiti lang ug http request/response headers. The complete details http://www.w3.org/Protocols/rfc2616/rfc2616.html.

Ang gamit sa headers kay mo return siya ug status like 404 for File Not Found, file size the, image type like jpeg, bmp.

Gamiti lang na ug web debugging.

sample code :

HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://localhost/myimage.gif");
request.KeepAlive = true;
response = (HttpWebResponse)request.GetResponse();
statusCode = response.StatusCode;
Console.WriteLine("\r\nThe following headers were received in the response:");

// Displays each header and it's key associated with the response.
for (int i = 0; i < response.Headers.Count; ++i) {
Console.WriteLine("\nName:{0} Value :{1}", response.Headers.Keys[i], response.Headers[i]);
}

The result is :

Name : Keep-Alive Value : timeout=15, max=100
Name : Connection Value : Keep-Alive
Name : Accept-Ranges Value : bytes
Name : Content-Length Value : 12697
Name : Content-Type Value : image/jpeg
Name : Last-Modified Value :Mon, 19 Mar 2007 17:21:10 GMT
Name : Server Value : Apache

or bisan nalang unta nga kung wala mo exist ang image, automatically the alternative image will be loaded or just a simple message or anything nga dili ma-notice sa mobasa nga wala mo exist ang image because just like internet explore they will mark X to those images nga wala mo load...
