I’ll combine two questions in one.
How can I center images within a topic?
And is there a module for creating an image slider inside a topic?
This Customization > Theme component adds composer buttons to center images Image Alignment and Grid. There is also Image Annotator - Allows you to annotate images in the previewer which adds the allignment buttons to the preview.
Did you take a look at the Customization > Theme component category? With the help of search it is quite easy to find those, which do someting with images. Maybe Slick Image Gallery is what you are looking for.

for centering images and text, you can also just use <div align="center"></div> like this:

Is this what you mean by a slider for images?
