Not necessarily. It depends on the chosen solution. The decision
between splash.pbm and splash.xpm is made in startup.el, based on
functions provided by image.el. So if I go on and hook the
Lisp-conversion into images.el (I guess that would be `create-image'),
it _could_ affect the choice of the image. Of course, I could also
make sure in startup.el that this does not happen. That's why I
asked. Another solution could be to use PPM instead of XPM for the
coloured image, which is, as Gerd said, always supported.
