The PNGs were corrupted when uploading, I uploaded them again in binary mode.
My Shadowbox nav controls are also not showing. I have specified an album in the link rel field, and Display Navigaton (in the Shadowbox Settings panel) is set to “true.”
The Shadowbox plugin does recognize that I have a gallery, because I can view all the images in the gallery using the arrow keys, but I can’t see the forward, backward and close buttons.
Is it a problem with the shadowbox css? I am using the Thesis theme, by the way.
