"We did not change the way the thumbnails are layout out."

- Piotr Gabryjeluk

You did change the HTML controlling the way the thumbnails were laid out, and you have now changed it back.

Right now, and before the change discussed here, the thumbnails were laid out like this:

Each .wikia-gallery-item is an inline-block element, which means the elements flow naturally, so that when I resize the page, it looks like this:

Earlier, during the period of time when the images were cropped, you changed the layout so that the .wikia-gallery-item divs were divided into rows by groups of 4, meaning that no matter the zoom level, it was 4 per row. This layout change was obvious to anyone using my NewFilesModule, as it caused the images in the module to also be displayed in rows of 4.

Unfortunately, I didn't take a screenshot of the source of that layout.
