Subject: RE: particle colour from map AND alpha over time
just connect your particle render tree up like this :-

the 'get color' node allows you to specifiy which aspect to override - in
this case the alpha.
so connect your particle gradient to particle color, over-ride the alpha
and then your texture map color comes through... WITH alpha.
