post - Upload Image to a Chevereto Website C#

A friend of my is trying to upload a image on a Windows Form App to a chevereto website, using chevereto API and trying to get the link back(response from website), but its not really working...

API: Chevereto API

UPDATE: Code Added

 static class Upload
{
    string apiKey = "DEFAULT_API_KEY";
    public string UploadImage(Image image)
    {
        WebClient webClient = new WebClient();

        webClient.Headers.Add("key", apiKey);
        webClient.Headers.Add("format", "txt");

        System.Collections.Specialized.NameValueCollection Keys =
            new System.Collections.Specialized.NameValueCollection();

        try
        {
            string ht = "http://";
            Keys.Add("image", ImageToBase64(image, ImageFormat.Bmp));
            byte[] responseArray = webClient.UploadValues(ht + "mysite.com/api/1/upload/", Keys);
            string result = Encoding.ASCII.GetString(responseArray);

            return result;
        }
        catch (Exception e)
        {
            InternalConsole.LogError("Cannot upload image, error on next line: ");
            InternalConsole.Log(e.Message);
            return "none";
        }
    }

    public string ImageToBase64(Image image, System.Drawing.Imaging.ImageFormat format)
    {
        using (MemoryStream ms = new MemoryStream())
        {
            // Convert Image to byte[]
            image.Save(ms, format);
            byte[] imageBytes = ms.ToArray();

            // Convert byte[] to Base64 String
            string base64String = Convert.ToBase64String(imageBytes);
            return base64String;
        }
    }
}

Can someone show me how its done?

Thanks in advance.

Nevermind guys, my friend already fixed the problem.

He used WebRequest to send and receive the data. He also said, dont forget to escape the string of base64(+, =, /), or the api will not accept properly and will return invalid base64 string.

Thanks anyway.
