I have a site where the user can add images to the content types page and (custom) project. These images are displayed in a views slideshow based on contextual filter on each page/project in a block. The slideshows are header slideshows, so there must be a placeholder slideshow, if no images are added. How can i accomplish this ? I need a solution where no further maintenance by the user is needed.
Do i have to put some if/else in the page.tpl.php or is there some more elegant way ?
