yeah 64x64 does look crude, that's why I used 128x128
ok so step by step, lets imagine you already have your background/ buildbutton template ok.
take a render of your ship on a black background
paste the render into psp
use selection modifiers to select only the ship and not the black
copy this and paste as a new image
resize the image to have a maximum length/width of about 110
copy the resized image
go to your button template and create 2 new raster layers
paste you ship into the 3rd layer it should still have a selection around it
click on the second layer
choose your glow colour
fill the selection area with your colour, you wont see it behind the ship
press select all
then use a gausian blur of between 4-8
save.
