This is the teaser section of the Post template of the Alpha theme. Upload images to show up in the slideshow or define the "Images Slideshow" variable to link to images of other pages. Define one of them as your teaser image by setting the "Image Teaser" variable. Note the other blog post below. You can define tags for every page or post in the Page Settings. Pages having tags in common with the current page will be shown as related pages.
