By default, the control has no picture associated. The control uses the PictureDisplay property to determine how the picture is displayed on the control's background. The BackColor property specifies a solid color to be shown on the control's background. The Background( exCalendarBackColor) property changes the calendar's panel back color if not-zero. You can use the EventsTransparent property to show the events in the control with a transparent color.

The following screen shot shows the control with a picture on its background (tiled):

The ExPictures collection holds a collection of icons, pictures that can be displayed using the Pictures and ExtraPictures properties of the Event object. The Images method loads icons to the control, HTMLPicture assigns a key to a picture object. The ExPictures collection can be accessed through the Pictures property of the control.

The control can display icons, pictures several ways as follows:

• Using the <img> HTML tag, if used in any label properties such as LongLabel or ExtraLabel property. The ShortLabel property can NOT display images or HTML font attributes. For instance, this option can be used to display a default icon or picture for all events in the control using the DefaultEventLongLabel property. Also, the <img> TAG can be used to any label or caption property that supports HTML format. 
• Using the Pictures property of the Event object, which indicates a list of pictures from Pictures collection to be displayed on the event's body. The PicturesAlign property indicates the alignment of the pictures relative to the borders of the event. The hand cursor is shown, if the ExPicture.ShowCursorHand property is set, when the cursor hovers the picture. The PictureClick event is fired if the user clicks a picture on event's picture. You can use the PictureFromPoint property to get the identifier of the picture from the cursor. 
• Using the ExtraPictures property of the Event object, which indicates a list of pictures from Pictures collection to be displayed on the event's body. The ExtraPicturesAlign property indicates the alignment of the pictures relative to the borders of the event. The hand cursor is shown, if the ExPicture.ShowCursorHand property is set, when the cursor hovers the picture. The PictureClick event is fired if the user clicks a picture on event's picture. You can use the PictureFromPoint property to get the identifier of the picture from the cursor.
