Is there a way to trim the summary or only render certain parts of a post?

Ideally I want to list posts with only their first corresponding images, no text. But if that isn’t possible I’d like to shorten the summary or manipulate what it shows somehow.

I’ve searched most of the documentation but can’t find anything that would apply. I know I could do this with some css+js, but I was hoping it would be possible out of the box.

Use <!--more--> as HTML comment in your post to split the content manually for the summary.

*facepalm* Thanks. I was overthinking it. I think I can get that to work.
