Thanks for everyone's replys. The solution works fine, although it's a
shame you need to know your background for a transparent gif )-;
I was wondering, is there a script-fu that would do this, i.e.
add a layer
fill with colour (parameter)
merge visible layers
select by colour (same parameter)
If not, is that easy to do? Maybe I'll learn scripts.
