Hello, I would extract the "Associations" tab from the images to another button in the toolbar since this window is called "Edit caption" (which does not relate to shop associations).
I'm not sure, that we'll be able to implement this suggestion in next Release.
For a while, it'll be great to vote for your comment to speed up the implementation. :-)
