pict & png should give me transparency, but they don't. anything I've missed on, maybe on the photoshop side? (I've prepared a single picture without its background)

In Max, you don't need to do anything to get transparent pngs to work. So it's probably on the photoshop side. Did you enable the alpha channel / transparency when saving?

In photoshop, put your object on a layer, and remove the background layer altogether. If you see the grey-white checker pattern in some parts, that's where it will be transparent when you save it as a png.

I thought I did all that. that's why I'm fairly clueless about why it's not working

At this time, jit.lcd does not support alpha transparency. You can use jit.qt.movie/jit.matrix->jit.alphablend or OpenGL.

that's good to know, thanks a bunch, ben!

I've been fooling around a bit. it appears to me, that in this particular case (transparency in combination with "face replacement"/cv.jit.faces) none of your suggestions will do.. due to the drawpict command I guess/my need for working with jit.lcd..

jit.lcd does not support alpha transparency AND there's no alternative to replacing cv.jit.faces' box with an image - am I right? (:

Ah, sorry about my somewhat misdirected suggestion. I assumed you were working with fpic, not lcd (didn't check your patch).

What would be the way to open a PNG and preserve the transparency in OpenGL?

It depends on exactly what you want to do, lots of ways to do this, but one simple example is to use videoplanes, layers and blend_enable 1:
