where does the variable named "fromlist" come from? It's not passed into
the method as a parameter.

You have:

>From the PIL docs, putdata does not appear to return an image. The docs
for putdata say:
putdata
im.putdata(data)
im.putdata(data, scale, offset)
Usually, when a PIL method returns an image, the docs say "=> image"
after the method signature. My guess is that putdata returns None, which
would be consistent with the error message "'NoneType' object has no
attribute 'show'."
You'll probably want:
newim.putdata(a)
return newim
Instead.
