I am creating a blog using the Autofocus template.
My aim is inserting a gallery into a post without a featured image (as shown on http://theme.wordpress.com/themes/autofocus/). Unfortunately the first image is always featured automatically. How can I change this? According to the forementioned site it should be possible to "showcase an entire set of photos then simply insert a gallery into your post without manually setting a featured image". Unfortunately I don't even set a featured image manually (knowingly).
The blog I need help with is kilianwasmer.wordpress.de.
