Charmian, I will ask the obvious. Is the Transparent Background checked in the png options? [image: SP3C_Transparent.PNG]

You need to add them as a collection then save the collection so SketchUp can load them each time it starts. There's a button in the Materials Browser that allows you to Add or Open as collection.
