There is, but you delete them. This is exactly parallel to writing Scheme code in an online Scheme system, but never saving it, and then at the end, writing out a standalone executable, quitting, and destroying the source. The fact that it may be common practice to destroy the source in image editors is lamentable, but doesn't change the relationship of the parts.
