It would be nice to have a 'PauseOnMouseOver' property on the RadImageGallery like the RadRotator have.

Especially in the case when the toolbar is hidden (<ToolbarSettings Position="None" />) and autostart is on : 

function pageLoad() {
                $find('<%=RadImageGallery1.ClientID%>').playSlideshow();
            } 

Thank You
