i cannot retrieve the user image .
DirectorySearcher searcher = new DirectorySearcher();
searcher.SearchScope = SearchScope.Subtree;
searcher.Filter = string.Format(CultureInfo.InvariantCulture, "(sAMAccountName={0})", Environment.UserName);
//SearchResult findUser = searcher.FindOne();
foreach (SearchResult findUser in searcher.FindAll())
{
if (findUser != null)
{
DirectoryEntry user = findUser.GetDirectoryEntry();
string userName = user.Properties["displayName"].Value.ToString();
string departement = user.Properties["Department"].Value.ToString();
string title = user.Properties["title"].Value.ToString();
string[] rt = new string[] { Login, userName, Email, Mobile };
Lbl_User.Text = userName;
Lbl_Administrative.Text = departement;
Lbl_Position.Text = title;
}
}

I've just taken your code and made a method out of it just to retrieve the image. You would need to refactor it, to either get only the byte[] or thw whole image.
//add this
using System.Drawing;
static Image GetPhotoFromAD(string userName)
{
DirectorySearcher searcher = new DirectorySearcher();
searcher.SearchScope = SearchScope.Subtree;
searcher.Filter = string.Format(CultureInfo.InvariantCulture, "(sAMAccountName={0})", userName);
//SearchResult findUser = searcher.FindOne();
foreach (SearchResult findUser in searcher.FindAll())
{
if (findUser != null)
{
byte[] photodata = findUser.Properties["jpegPhoto"].Value as byte[];
using (MemoryStream str = new MemoryStream(photodata))
{
return Bitmap.FromStream(str);
}
}
}
}
If you only want the raw data, the important bit is byte[] photodata = user.Properties["jpegPhoto"].Value as byte[];

Answer 2

The binary image should be stored in property called thumbnailPhoto.
var photo = user.Properties["thumbnailPhoto"];
if (photo != null) {
byte[] buffer = (byte[])photo.Value;
//var bitmap = new Bitmap(new MemoryStream(buffer, false));
//bitmap.Save(#"c:\test.bmp");
}
Now, given the fact that you tagged question as asp.net you'll have to write generic handler (.ashx) for retrieving the image. This handler should write content of
photo.Value
into response output stream and set content type to image/bmp
In your control/page just reference the handler like
<img src="/GenericHandler.ashx" alt="My image" />
