[Theme: Twenty eleven] Background image in footer moves text

Hi!

I have created a childversion of theme twenty eleven and custumized it a lot. But i have a problem.

After I added a backgroundimage in my footer
<img src="https://seaskonst.se/wp-content/uploads/2013/08/menu.png" width=100% height= auto>© 2013 Sandra "Sea" Ekstr?m | <a href="mailto:[email protected]">[email protected] </a>
(created a new footer.php in my childtheme) the text that i have in the footer aren’t anymore in the center, it kind of slided down a bit. It’s still over the backgroundimage but not centered.

I’m not new to code but I’m totaly new to wordpress
somebody have any idea why this happens?
