J3.0 Editor changes text

I have a default hot_tennis installation. When i add an image to an article <img src="images/logo1.png" width="99" height="80" /> and save the article the code changes to <img src="\&quot;images/logo1.png\&quot;" width="\&quot;99\&quot;" height="\&quot;80\&quot;" />

I already had a look to the text filter and i already tried it with "no editor". Every time the code changes.
