This is one of the heuristics I use to judge the trustworthiness of newspapers and magazines: do they choose photos of people that make them look like idiots? If so, their bias may show up in more subtle ways, too. Whatever you think about the possibility of objective journalism, an editor can do better than choosing a demeaning photo of someone they don't like.

It is a well known open secret in the newspaper industry that if you want to make sure they use a bad photo of you, just be a jerk to one of the journalists. They talk to the photographers.
