Voila!
function pngIsTransparent pImageFile
if not (there is a file pImageFile) then return "ERROR: Invalid file path!"
set the filename of the templateImage to pImageFile
put numtochar(0) into tZero
return (tZero is in the alphaData of the templateImage) OR (tZero is in the maskData of the templateImage)
end pngIsTransparent
