Sorry, I mixed inputDate and inputCalendar... Instead of the button, I can use an image for the popUp using these attributes popupButtonImageUrl="images/calendar.gif" renderPopupButtonAsImage="true"
But how to change the images _inside_ the popUp calendar? I mean the close, left, right and down images. In CSS there is a hint "Note: The right, left and down icons are images, jscalendar-DBich must be edited if you need to change them.", but I don't understand, what to do. Kind regards Holger
