Lücke zwischen oberen und unteren Hintergrund

Hallo,

ich weiß nicht wie ich es genau erklären soll,
aber der obere Teil des Hintergrundes und der Content Hintergrund teil kommen nicht ganz zusammen... wenn ich mir die Theme Vorschau im WP-Admin Bereich anschaue sieht es normal aus, aber sobald ich das Theme aktiviere ist da eine ca. 2 cm breite Lücke, als wäre die Content-Top.jpg etwas nach unten gerutscht auf dem Background.jpg

Wird das in der style.css bestimmt?

Ich kopiere den Inhalt mal hier rein, (es geht um Background.jpg und Content-top.jpg):

Könnt ihr mir vielleicht weiterhelfen?

Edit:

Unter 02 Structure habe ich die 172px in 144px (bin schrittweise nach unten gegangen) geändert und dadurch hat sich die lücke geschlossen... ABER jetzt ist der content-top.jpg teil im vergleich zum background.jpg um ca. 1mm nach links verschoben, dh. es passt nicht mehr so richtig von der grafik her... woran könnte das denn liegen?
