You need to pass the Image in a POST request to the Graph API (Need publish_stream permission). What is mentioned in Facebook Documentation is correct. Following is the example code that may do the work. use it inside a method. (Code is in C#)
Legend
<content> : you need to provide the info.
Update
Please post comments to improve the code.
string ImageData;
string queryString = string.Concat("access_token=", /*<Place your access token here>*/);
string boundary = DateTime.Now.Ticks.ToString("x", CultureInfo.InvariantCulture);
StringBuilder sb = String.Empty;
sb.Append("----------").Append(boundary).Append("\r\n");
sb.Append("Content-Disposition: form-data; filename=\"").Append(/*<Enter you image's flename>*/).Append("\"").Append("\r\n");
sb.Append("Content-Type: ").Append(String.Format("Image/{0}"/*<Enter your file type like jpg, bmp, gif, etc>*/)).Append("\r\n").Append("\r\n");
using (FileInfo file = new FileInfo("/*<Enter the full physical path of the Image file>*/"))
{
ImageData = file.OpenText().ReadToEnd();
}
byte[] postHeaderBytes = Encoding.UTF8.GetBytes(sb.ToString());
byte[] fileData = Encoding.UTF8.GetBytes(ImageData);
byte[] boundaryBytes = Encoding.UTF8.GetBytes(String.Concat("\r\n", "----------", boundary, "----------", "\r\n"));
var postdata = new byte[postHeaderBytes.Length + fileData.Length + boundaryBytes.Length];
Buffer.BlockCopy(postHeaderBytes, 0, postData, 0, postHeaderBytes.Length);
Buffer.BlockCopy(fileData, 0, postData, postHeaderBytes.Length, fileData.Length);
Buffer.BlockCopy(boundaryBytes, 0, postData, postHeaderBytes.Length + fileData.Length, boundaryBytes.Length);
var requestUri = new UriBuilder("https://graph.facebook.com/me/photos");
requestUri.Query = queryString;
var request = (HttpWebRequest)HttpWebRequest.Create(requestUri.Uri);
request.Method = "POST";
request.ContentType = String.Concat("multipart/form-data; boundary=", boundary);
request.ContentLength = postData.Length;
using (var dataStream = request.GetRequestStream())
{
dataStream.Write(postData, 0, postData.Length);
}
request.GetResponse();
