Perhaps offer it as a setting, that users could potentially turn on/off?

It’s just that, IMHO, there’s no point in having Profile Images, if you’re not allowed to zoom in /out, and see them up close.

In Reddit, if, while scrolling through posts, you tap on a post that contains an image, and then swipe upwards, you are able to access the comment section, without having to click on the comment section button.
