I can think of two things   First  try loading the image with   string strUri2   String Format   pack   application     MyAseemby component resources main titles  0    CurrenSelection TitleImage   imgTitle Source   new BitmapImage new Uri strUri2      Maybe the problem is with WinForm s image resizing  if the image is stretched set Stretch on the image control to  Uniform  or  UnfirofmToFill    Second option is that maybe the image is not aligned to the pixel grid  you can read about it on my blog at http   www nbdtech com blog archive 2008 11 20 blurred-images-in-wpf aspx
