In my opinion, the MSE community could benefit a lot from being able to scale down images in answers and questions. Often images get unintentionally huge, which prevents users from seeing as much information as desired at once. It is also tiring to scroll up and down to get to the different parts at the question. Currently images and words aren't working well-enough together, and I'd like to fix it.
After talking to @robjohn and @Ted Shifrin I came to the conclusion to post my suggestion here on Meta. Quoting @robjohn:
I am not sure how that would go over with the devs, but definitely something could be suggested in meta.
I am imagining simple commands, for example
scale = 0.5, which then scales the picture to a half of its original size.
