i beleive he means his image planes are not showing ...but i could be wrong ..

he is talking about how kurt puts an image on a plane and then when to switch to that view to see it ...hits 6 on the keyboard and it is visable ..

one thing in your pic ...cut ..i dont see the image plane you setup ? you had to make a poly plane first ..and then go to hypershade options and then lambert and then attach your image ..then you middle mouse drag it onto the plane you have created ..in the picture you setup i dont even see a plane ?
