It would be good to at least have some marker added to artworks which are animations/gifs. Right now when I visit https://lospec.com/gallery/medium:pixel-art/time:all I see only static images and I might not decided to click on some piece because I don't know it is more interesting when animation is playing. If it was marked as GIF, I would click to visit its page and see the animation or at least hover with mouse over it with hope to see a preview of the animation
