i need to know how to put more than one picture in a post lightbox gallery.
when uploading a new image by using the media library/"add files option" the picture is not displayed in the lightbox gallery. only as wordpress standard picture. there will be no second preview picture in the lightbox gallery and only the standard full size picture appears.
hopefully this picture will describe my problem: http://screencast.com/t/NGjLq6E3Y0
what do i have to do?
