You should be able to use 'the templateImage' (see dictionary), and
numToChar probably should be numToByte
As in:
on mouseUp
answer file "Pick an image:"
if it is empty then exit to top
set the filename of the templateImage to it
put numToByte(0) into tZero
put (tZero is in

I usually make things harder than they need to be, so I'm asking: Is
there a simple way my LC code can determine if a PNG image is completely
opaque or not?
Thanks -
