Oh that was probably me. I didn't actually look to see if it was a rule here, because most news communities already have it.

Images definitely shouldn't be allowed, because they're just not reliable sources. Even if it's a screenshot of an AP story, it doesn't let us read the actual story. For all we know, it could be completely fabricated. And it's not accessible to people using screen readers or whatever.

Video news I don't really like, I just prefer text. As long as it's a reputable source, not some random non-credible person on youtube. Especially in the US, local affiliates of national news networks like to just clip their broadcasts and post them as articles.
