The same picture is showing twice?

Hello

I work with the theme Minimatica.
Every time I place a picture into a post, it will be shown twice.

For example, like this:
http://wewerehere.dk/?p=219

I have tried to change the settings with ‘gallery’, ‘standard’ and ‘image’, but without success.
Does Anybody know how I can change this?

Actually I would prefer to create an album at the bottom with 5-10 images each time, but this function does not quite work.

I supposed to be blogging all from a Ipad, just for info:)

Daniel, on your page shows you a layout with a broad picture at the top. “Kitty eyes” how can I fix that?

Thank you in advance for your help.
