I’m aware of the components to set a featured image by picking one of the images in the topic, but is there any other option similar to Wordpress where we can upload an image as featured without it being in the topic itself? I pretty much would like to use it as the open graph image, but not necessa…

ChatGPT’s solution seems to work: [image] And Facebook Debugger sees it as the featured image: [image] Component with the Javascript: import { apiInitializer } from "discourse/lib/api"; export default apiInitializer((api) => { api.onPageChange(() => { document .querySelectorAll('…

What is a “whisper” in this context?

Can we change the “wrap” from “hidden” to something more custom that would avoid any danger that @Jagster is thinking about?

The image is only hidden from being shown. It’s still there, just not visible when you look at the topic. You can make the CSS more specific so it hides not everything, but for example only images or even only images that are specified as a thumbnail. My example: The post: testing [wrap=hidden-…

The threat scenario here is, or is for me, that someone hides something that googlebot hates. It would be an easy way to sabotage SEO etc.

You can also hide stuff in posts with other techniques Like  There is one below: So I don’t think the wrap syntax is a problem

This particular thing is just for me to use on specific categories. It’s not something I’m allowing other users to do.

But this would be seen as a comment, not an image, right? When it comes to the open graph.

So basically the wrap data can pretty much be anything I want? This seems like a good option.
