This method can be used to test if the image has been modified, and therefore needs saving/storing in an unbound or external-files solution. Alternatively, you can handle the ImageModified event to save the image directly whenever it is modified. An image is modifed when editing (eg rotate, resample), deleting/clearing, or loading, pasting or acquiring a new image. The image is initially 'opened' when it is loaded by data-binding, asigned to the Image property, or displayed using ImageViewFile or ImageViewBlob. See also: ImageModified event ImageChanged event
