I've placed an image at the top of my site, below the WordPress admin bar (wpadminbar).
When you're not signed in, everything looks fine: http://share.xboxlife.dk/file/n2vmyjmxnzvknjg2zwrlnmm4zjrhnzm1nwvizgy1ywq.jpg
But when you're signed in, the image doesn't move down a bit down, so that the space between the image and the top of my site gets smaller: http://share.xboxlife.dk/file/owrlndu0mwm2odfhymzjnzq1njbin2e5otewnguymti.jpg
What do I have to do so that the size of the space is equal when you're signed in and not.
