PSA: Inline image/photo comments enabled as an experiment

Up until now, the mod team has disabled the ability to add photos or images to comments, as a way to reduce spam and low-effort memes. Recently, several legitimate use cases for photos in comments having arisen, like a case where someone needed help with some brokerage screens and needed to share a screenshot to help explain what they were seeing. Let's test the waters as a community for a week and see how things go. We'll evaluate the results over the next 7 days. We are NOT enabling inline videos in comments. That is a new feature being rolled out site-wide and which prompted this experiment. NOTE: Photos and inline images have **always** been enabled in posts, but by Rule 8, we filter out posts that are **only** a photo, or that are *mainly* a photo with very little text. In posts, photos should support the text content, not the other way around.
