The cod snippet you'll get in snail mail. (Snails? Cod? Sounds
vaguely French......)

Anyway, here's the code snippet.

;maxlat = maximum latitude of grid
;minlat = minimum latitude of grid
;maxlat,maxlon = same for longitude
;image = byte array to be written to Geotiff
;xsize = # columns in image
;ysize = # rows in image
;outfile1 = output filename

scale = double([(maxlon-minlon)/xsize, $
(maxlat-minlat)/ysize, $
0.0])

tiepoints = double([xsize/2.0,ysize/2.0,0.0,(maxlon+minlon)/2.0,
(maxlat+minlat)/2.0,0.0])

gtiff = {modeltiepointtag: tiepoints, $
modelpixelscaletag: scale, $
gtmodeltypegeokey: 2, $ ; Geographic model type
geographictypegeokey: 4326, $ ; WGS84
gtrastertypegeokey: 1} ; pixel represents an
area

write_tiff, outfile1,reverse(image,2),comp=2,geotiff=gtiff ;
reverse may not be necessary for your images
