and https://www.npmjs.com/package/nodebb-plugin-simple-spoiler
Text and image alignment in the first one, a simple spoiler that allows you to name them and stack them inside each other in the second. Both built for default composer and super plain so you can style them as you like.
same as other plugins - they're for my personal site so no guaranteed support.
