You could consider aligning the "arrowcontrols" to the stage borders(and close to them) to avoid the descriptions text overlapping the "next" button. This is not important of course, because the arrow controls autohide after mouse inactivity anyway.
The menu indicated there are [3] images in "Hell dorado miniatures", but it seems you may have moved those files to a subfolder? You should therefore click "Clear cache" in the admin so that the filecount updates.
