So this might not be the result of ASRI, but when I disabled the plugin it stopped happening. So I think it would be worth investigating.
I created a post with a photo gallery. The images were not separately inserted... they only appear within the post [gallery].
I noticed that every time I update the post, a new empty photo appears within the gallery.
(under the screen where you can see the members of the gallery and edit settings Edit Post > Visual Editor > select gallery > Click the photo icon to edit).
