How to move the image at the home page?

Hi there,

I have a question about my home page. I just did some updates, when suddenly (probably it is not suddenly, but I’m not so good with WordPress), the front page changed. The image that is shown overthere, moved up. Now I can’t figure out how to get it back down. I want half of the dandelion shown (without the hand), so the text is readable and I looks better. The image is not placed in the header.

Here is the website I’m talking about: www.kinderpraktijkvota.nl

Hopefully someone could help me.

Thank you.

Katinka
