I use this in an application currently. Content URL is passed in as a query string value (the URL to the image).

try
{
    if (ContentUrl != "")
    {
        string imgExtension = ContentUrl.Substring(ContentUrl.Length - 3, 3);
        switch (imgExtension)
        {
            case "":
                //image/bmp
                Response.ContentType = "image/bmp";
                break;

            case "jpg":
                //image/jpeg
                Response.ContentType = "image/jpeg";
                break;

            case "gif":
                //image/gif
                Response.ContentType = "image/gif";
                break;

            default:
                Response.ContentType = "image/jpeg";
                break;
        }

        if (!ContentUrl.StartsWith("http"))
            Response.BinaryWrite(new byte[] { 0 });

        WebClient wc = new WebClient();
        wc.Credentials = System.Net.CredentialCache.DefaultCredentials;
        Byte[] result;
        result = wc.DownloadData(ContentUrl);


        Response.BinaryWrite(result);

    }
}
catch (Exception ex)
{
    Utility.WriteEventError(Utility.EVENTLOG_SOURCE, string.Format("ImageProxy Error... Url:  {0}, Exception: {1}", ContentUrl, ex.ToString()));
}
finally
{
    Response.End();
}
