Re.: Position-6 (Best In Class, Our Fleet, Our Mission)

Hi AS Team,
how can I change the pictures. Where can I find the class mentioned in:
<img class="featured" src="images/sampledata/asimage/featured/featured.thumb.1.jpg" alt="" />. When I added new pictures named, "featured.7.jpg and featured.thumb.7.jpg, into the appropriate folders and amended the path accordingly I haven't been successful. Is there a component to load up the pictures or how does this work.

Best Regards
skipper
