IIRC the specification for GIF87 says that the first palette position is
for transparency. (assuming that is what you meant by 'where')

If you specify colour x on an image is transparent, it get's pride of
place.

Have Fun

Nope ;) I meant "where" in the gif image itself (I'm just kidding
around), but glad you pointed it out about the palette for those still
wondering about such things (if they do). I had tried before, in vain,
to edit the palettes of my custom startup logo screens to get those
elusive animation indexes to go into them too and always failed. Now I
guess I know why, that talk of the hex editing instead. I simply
expected the index to remain usable with whatever changes to the colors
made so long as the index numbers remained as in the original MS Startup
Logo screen. Going to look up that utility for doing it right and maybe
do some more of those things. Fun to manipulate ones computer
environment for the better.
Just happened to look up at the Subject line. Began to think I was in
another thread here. Sorry, OT.
