Displaying images outside the content

I’m not sure how you used the block editor for this. However, I would have the article be the width of the content, make the container the text content is in the size that you need it to be, and have the images be the width of the container.

Styling would depend on the blocks used.

For example:

<article> <--- full width of content
<section><div></div><aside></aside></section> <--- section width needed
<div><img><img></div> <--- full width
</article>
