Getting a image plane to show in wireframe mode?

[saken]

I'm using Rhinoceros 3D, and I simply cannot get the image plane to show itself in wireframe mode in a viewport.

Can someone tell me how I can achieve this?

Simple Just right click on the name of the viewport (left, right, top, or perspective) and a menu will appear, where you can select wireframe, shaded, ghosted, rendered ecc. Rhino's really easy, once you get the hang of it!
