The Height property is initialized with the height of the loaded picture, once the Add method is called. You can use the Height/Width property to change the size of the picture when it is displayed on the event's body using the Pictures and ExtraPictures properties. If using the <img> HTML tag to display the pictures/icons, the <img>pic1:32</img>, the 32 indicates that the size 32x32 should be used to display the image.
