I am reading the image from Active Directory the Property["thumbnailPhoto"].

My Model assigns it to this:

public Image thumbnailPhoto { get; set; }

My Service runs this code to put get the image from Active Directory and put it into my Model.

public Image GetUserPicture(string userName)
        {
            using (DirectoryEntry de = new DirectoryEntry("LDAP://server.com"))
            using (DirectorySearcher ds = new DirectorySearcher(de))
            {
                ds.Filter = ("(&(objectCategory=person)(objectClass=User)(sAMAccountName=" + userName + "))");
                ds.PropertiesToLoad.Add("thumbnailPhoto");
                SearchResult rs = ds.FindOne();
                using (MemoryStream s = new MemoryStream(rs.Properties["thumbnailPhoto"][0] as byte[]))
                {
                    return Bitmap.FromStream(s);
                }
            }
        }

I call the above method and assign it to the Model from this line:

user.thumbnailPhoto = GetUserPicture(rs.Properties["sAMAccountName"][0].ToString());

This all seems to be working, no errors, I can see in the debugger that user.thumbnailPhoto is of type System.Drawing.Bitmap.

Where I am stuck now is how to display this on a webpage?

Is it possible to throw this thumbnailPhoto into a Session["UserPhoto"] since I will need it on every single page?

You will have to create helper action that returns content of the image and reference it in your model by some ID (userName?). –  Ilia G Jun 13 '13 at 15:28
    
"Where I am stuck now is how to display this on a webpage?" - Are you displaying the image, or a string that represents the image type, like "bitmap" or "jpg"? –  mbeckish Jun 13 '13 at 15:29
    
Well when I throw it into a Session and then replace my blank image with the session. It just shows System.Drawing.Bitmap on the webpage. @mbeckish –  James Wilson Jun 13 '13 at 15:33

I would convert it to a Base64 string then use that as the source.

   using (MemoryStream s = new MemoryStream(rs.Properties["thumbnailPhoto"][0] as byte[]))
   {
       byte[] imageBytes = s.ToArray();
       string base64String = Convert.ToBase64String(imageBytes);
   }


   <img src="image/png;base64,@Model.ImageBase64String" />

I tried this but it doesn't seem to be displaying the image. It's just a broken image box. Here is the HTML it creates. It creates a massivly long <img> tag however. The only difference is I am putting the image into a session variable. –  James Wilson Jun 13 '13 at 15:46
    
The Base64 string will be very long indeed. –  Gabe Jun 13 '13 at 16:12
    
Make sure the mime is correct, if its not a png, use the correct type... –  Gabe Jun 13 '13 at 16:13
    
Yep they were Jpeg's fixed the issue. Thanks! –  James Wilson Jun 13 '13 at 16:52
