the image that was once here is completely lost, its now a "no war" image with the ukrainian flag. but idk if this even still works, i'll see if it does.
sorry for late response, but
i’m assuming it was a picture of a checkbox to toggle comments on or off; now there’s a speech bubble icon in nicovideo’s videos to toggle comments
imageshack, the host providing the image deleted all images for non-premium users and were replaced with advertisements; now imageshack is just saying stop the russian invasion on ukraine
also registration is no longer needed to watch videos, for other people
