How to align the box with an image without interference of the text?

Hi,

Great plugin, I love it and it’s very simple to use!

However, I can’t succeed in putting the box on the same level as an image without my text interfering between the image and the box.

See here : http://www.labasesecrete.fr/blog/?page_id=43

The paragraph doesn’t start under the picture, like I would want it to, but right near it and the box.

I’ve tried multiple variant of plugins allowing to make jumplines but it doesn’t fix my problem.
