2.5 See background image through objects?

How can you see background image through objects?

I’ve seen tutorials for 2.4 where you can set blend to see through objects but I can’t find it on 2.5.

Thanks for the help,

You can just select wireframe mode or select Transparency in the Object Display settings and give your object a semi transparent material

Sorry I meant see the background image while modeling so I can copy the shape of something.

Like on Blender Cookie’s Modeling a Porsche 911 GT3 RS.

All the same background image properties (location, transparency, view), and more are in the Properties panel (N)
