Hi All I was wondering whether it was possible to use alpha planes in Poser.

I wanted to put an image on a Plane without the Plane showing and I can't work out how you do this.

Yes, you can do this.
You'll need to make an image out of the alpha channel to use as a transparency map.
Once you say which version of Poser you're using, it'll be possible to give more precise instructions.

I use Poser 6 and my idea is to have the image of a motorcycle on an alpha plane with a poser figure straddling the motorcycle

I shall get busy now and study and try out the  information that you have kindly given.

Good luck!

If you get trouble getting the shadows right.  Make an IBL lightset based on the photo of the bike. Then using this lightset, render the rider without the alpha plane or background.

Save the render as a transparent PNG and in PhotoShop/Paintshop Pro etc. Paste the rider render over a copy of the photo as a transparent selection. Now postwork in the shadows with something like the shadowlab from Alien Skin's Eye Candy filter. Then use the zoom, eyedropper and pen tools at 1 pixel to postwork out any jaggies. 

Another trick for adding real human faces is use a model bike and model rider then postwork in the human face afterwards. As the figure would be in leather you wouldn't have to worry about matching skin tones.

If you wanted the correct sponsors logos on the racing leathers then just add these to a copy of the original leathers maps.
