JPG format is not working but BMP is OK

I am trying to display a bitmap image on the UI but it doesn’t work if I use a JPG file in the resources. BMP works fine but the files are 25 times the size.

Smaller bitmaps seem to work fine. The test one is 445 x 500 pixels. I preload the bitmap when the class is created and then use this code to draw the bitmap onto the Image.

            clockDisplay.Clear();
            clockDisplay.DrawImage(number0, 0, 0);
            clockImage.Source = BitmapImage.FromGraphics(clockDisplay);
            clockImage.Invalidate();

This what is looks like with BMP format in the resources.
