Charles,
I went to this site in a few spare moments and I think it looks great. I
hadn't looked at the GD stuff at all, but now I think I might explore it,
particularly for graphing functions.

Chris's note about recent versions of GD supporting PNG graphics is
timely, as Unisys is trying (again) to enforce it's patent on the
compression used in GIF images. PNG might be the way to go. See
http://www.macintouch.com/giflicensing.html  for more info on recent
developments.

Thanks for working on the tutorial. I look forward to reading it in
greater depth later.

Geoff
