How to display custom images in an article?

Question

MODX

Good day.
Help plz, I can't figure out how to display custom images in an article.
There can be a different number of pictures, from 0 to 100+
Pictures are half-screen wide and are located either to the left or to the right.
They have a different class that moves them left / right (maybe you need to set 2 different templates).
And each picture should be able to fill in alt=""
Plz tell me, with what plugin is this done?
UPD In this particular case, we managed to rewrite the styles and get by with pseudo-elements to style all the pictures in the article. And left / right alignment can be set directly in the editor when an image is inserted.
