Forgot to mention that... I used Imagine originally.  LW doesn't have a
function like that.  Simply put, in Imagine you used images with a color
map (2-256 color pics).  The first color in the palette (color 0) is made
transparent.  24-bit images do not have color maps, so that won't work.
Since it is assumed you asre always using 24-bit images, it seems that
they thought that feature would not be missed too much.  Oh, well...

I would like the ability to pic a key color -- almost a chromakeying
thing for image maps.  You pick, say, color values 0,0,0, to 0,0,255, and
all the blue gets cut out of the image.  Anyone wanns write a plug-in (or
re-qrite LW :) ) to do that?
