The Pictorial History of Grandview (available both from the Main Menu and the sidebar) has not been working properly for a while. It was a mystery to us why. However, it now appears that WordPress has disabled it due to a security flaw, and the original developer of the gallery software is no longer supporting it.
We have not yet found an equivalent gallery software that allows an automatic slideshow. However, we have adjusted the view that now allows all the images to be shown. Click on any thumbnail and you should be able to go backwards and forwards through the images.
Sorry for the delay on this; we are historians not technicians!
