You're misreading what I wrote; the point of mentioning reading/writing
is that an `image' in Emacs lisp is just an ordinary lisp value, which
can be stored to a file (using print or whatever), and read back into a
new session.
Previously, the value returned by `create-image' was a valid image,
which could be displayed, even if saved to a file and read back in a new
emacs session. After your change for windows, this was not true any
longer. This was a regression, and my change was intended to fix it.
