For some special cases, I prefer the versions below.

if any([
not isinstance(src, Image),
mask != None and not isinstance(mask, Image),
not isinstance(dest, Image),
]):
raise TypeError("image args must be Image objects")
Or equivalently:
if not all([
isinstance(src, Image),
mask is None or isinstance(mask, Image),
isinstance(dest, Image),
]):
raise TypeError("image args must be Image objects")
