When viewing the contents of this file (myserver>styles>default>xenforo>node-sprite.png) there are four images there. How do I make the node icon use the sheet images instead of the bubble images? I would have expected the two styles to be in different files so each would have a defined location. SP>Node Icons> Node Icon Forum and SP>Node Icons> Node Icon Unread Forum both call the same image file. How does the read/unread change work? If CSS handles this, why are there four images?
