I know that the first images in an article are not always used in the hovercards due to the image proportions, size or quality. However, these factors always seem to be changing. For example, in the articles: Nirvana In Fire, Legend of Nine Tails Fox, and The Journey of Flower, all of the images used in the infobox were adequate enough to be put as the image in their respective hovercards. However, in the last few days, the images have not been shown in the hovercards, and since the images are still used in the article, I feel that it's because the Hovercards do not accept pictures with those proportions or quality anymore.
But why? The images were perfectly fine before, but now they are unusable in the hovercard feature. Is there any way to let those pictures be used again in the hovercards? Plus it will be very nice to know what proportions and qualities that are allowed. Thanks
By the way, still love how helpful the hovercards are, but the image can be a very helpful visual aid.
