I have a wiki on which many pages have a <gallery> in the image part of the infobox.
As you can see, the infobox has 2 images: one saying "MZ Entertainment", the other one saying "The Music Works".
When I go to a category page containing this page, or when it gets trending, whatever, the "The Music Works" image is shown as the preview. I'd like the "MZ Entertainment" one to show up as the preview instead.
How can I change that?
