Here is an example of a texture that was mapped to a plane. I use displacement in order to make the object actually project into 3-dimensions. You can tell from the specular highlights especially, that the texture does not lie flat on the plane.

I used ShaderMap in order to generate the Displacement map, simply from the initial texture... To use it in Blender, use one texture channel for the Diffuse Map (simple image) and another texture channel (with Color at 0 and Displacement at very low... 0.05 or so) for the displacement map.



Enjoy!
