Are you attempting this with Jpg? No, not likely if you even half know
what you're doing. Far as I know, and I know only a tiny bit, Gif is
the only thing that works for the typical browser. May be that Png
will sometimes if not always, I just don't know. Besides that, do not
use a 'sky_sphere' or 'background' color (nothing or a plane instead
for example) and try the alpha channel out if you can. The DOC will
explain somewhat. Others here probably have a better game plan, but
what I'd do is select a transparent color for a Gif in a image
processing program is all.
