Hi! Awesome theme. I have a gallery page that displays my portfolio items. On the demo page here: http://www.kriesi.at/themes/flashlight/portfolio-3-columns/, the portfolio page displays thumbnails for each portfolio item. I have created a page and added some portfolio items, however, my thumbnails are not displaying. See here: http://saddlebackstudios.com/2013/?page_id=35.
Is there a selection that I'm missing or are these thumbnails automatically generated?
