I try to read the PropertyItems of an jpeg image which contains a lot of properties.
I allways get "0" as a result of the following code.

// parametres exif
Image img = new Bitmap(fichierOri);
PropertyItem[] propItems = img.PropertyItems;
la_message.StringValue += ("\n*** " + propItems.Length.ToString ());

We don't have 100% coverage for System.Drawing in Mono.  A couple options for alternatives would be https://github.com/mono/sysdrawing-coregraphics for a version of System.Drawing implemented with CoreGraphics under the hood, or else using NSImage/CGImage and apple's APIs to get the information.
