So, what tool do you use to create this file, say, by converting a PNG?
I've used something like this for converting a GIF using NetPBM tools:
#!/bin/sh
# Make a favicon.ico file from an input file
# Currently only works for square input files: you have to crop to a #square
giftopnm input.gif > tmp.ppm
pnmscale -width 48 tmp.ppm > tmp48.ppm
pnmscale -width 32 tmp.ppm > tmp32.ppm
pnmscale -width 16 tmp.ppm > tmp16.ppm
ppmquant 256 tmp48.ppm > tmp.ppm
mv tmp.ppm tmp48.ppm
ppmquant 16 tmp32.ppm > tmp.ppm
mv tmp.ppm tmp32.ppm
ppmquant 16 tmp16.ppm > tmp.ppm
mv tmp.ppm tmp16.ppm
ppmtowinicon -output favicon.ico tmp48.ppm tmp32.ppm tmp16.ppm
/bin/rm tmp48.ppm tmp32.ppm tmp16.ppm

Richard.
