I dont really understand these g4particle images. they show some very interesting properties... they appear to have detail in the image preview on windows XP, but when i open it in paint shop pro, it looks totally different. the most signifigant thing is the black background which is obviously shown white in the preview, as if it was a transparent color, but on a 24 bit png?

can someone who made the existing particles explain to me the process of making proper particle images. thanks
