How to find out whether an image is displayed anywhere?

[Lars Magne Ingebrigtsen]

I just noticed that animated images keep on being animated even if the
images themselves aren't displayed in any buffer.

That seems wrong.

Is there a way to query Emacs whether an image is actually displayed
anywhere?  I looked through image.el, and I couldn't find anything...
