DrawImage Graphics3D

If I use DrawImage in 3D-mode, will the alpha byte be used for partial transparity of the image? Or must I create a texture and wrap it onto a flat 3d-object? (I really just want alpha in 2d)..

You could stick the image on a 3D sprite or any other entity, and set the EntityAlpha command to achieve transparency.

I've seen at blitzcoder a rather good library (source included) on about how to use 3D sprites for this particular purpose.
