Oh!? I'll have to dig deeper in my research.
If my {danube|shuttle}-splash.rgb files are actually 8-bit alpha, and they
work for me, and I haven't heard any reports of problems, then that would
discount my conclusion.
That would however, explain why my splash files are larger than desired.

no. it loads fine.
Yes, identify shows it as 8/8/8/1.
I can't tell if it is or isn't.
Gimp doesn't have an info panel that shows alpha bits, but using the color
picker, I can't find any pixels with an alpha less than 255.

Ooops! That was a sloppy mistake.
I might actually promote my work in the _negative!_
Actually, I didn't have the an2 installed, so just copied the splash.rgb over
to my model directory for testing.
I hear a complaint my models are too big.
...
I can't disagree with that.
Thanks to this thread, I have shrunk my image files by 1/3
Yea!
Would it also help if I gut the interior and doors, and release a smaller,
(less functional) version?
I think I'm better off just making a new model from scratch that can be GPL'd.

That'll take days. I was waiting for the next tarball point release before I
break my system. ;)

Ah, very nice then. :)
