Hmm - just a quick thought: You can't view anything you don't have - so you allways have to first "load" it (down-/up-/whatever-). Gmail has your email on the server so they can show you a preview before YOU download it to your machine from there site - right?

Solution 1

you can try the Bitmap object from System.Windows.Forms:

Bitmap normalBitmap = new Bitmap(filePath);
Image minimizedThumbnail = normalBitmap.GetThumbnailImage(200, 200, ()=>false , IntPtr.Zero);

Good luck!
