How do I make a transparent tga file in Photoshop? The tga file included in the source code of the tutorial from Lighthouse 3d is working fine but the files I am making are being loaded with the transparent part being white.

I am using the code from here (http://www.lighthouse3d.com/opengl/billboarding/l3dbillboard.zip)

1) create image
2) in the "channels" palette, click the "new channel" button
3) paint into the alpha channel
4) Save As... TGA - 32-bit - no compression.
