reference images not showing

I’m currently tying to do the Joan of Arc tutorial, but when I try to put the reference images into the viewports I see nothing. Is it a bug in blender or just me?

Thanks in advanced :stuck_out_tongue:

The only thing coming to my mind is that the view is not orthographic and is not side/top/front/camera view.

I setup everything right, but it still doesn’t show for some odd reason.
