When relating mouse events to images, it is necessary to know the position of an image within the control displaying it, and these properties provide that information.  They represent the location of the top left of the “cell” displaying the image.

In order to locate the image occupying a given location, use the ImageIndex method of the control.

The top left of the image “cell” may not correspond with the top left point of the image displayed if the image has been scrolled - see ActualScrollX and ActualScrollY for more information. Also, in many cases the ImageXPosition and ImageYPosition methods provide a simple method of calculating image pixel positions.
