> So, my question still is: the image being picked is always the topmost image in the topic? Is it how Discourse it built? Or is it randomly picked? And are there any specific requirements for it to pick the image in terms of image dimensions, etc? Just want to make sure that when it comes to my own topics, if I want to include images, I format them properly.

May not be the best place for this brief documentation, but you can use a `|thumbnail` hint in your image Markdown to choose a different thumbnail:

> [@Topic List Thumbnails](https://meta.discourse.org/t/topic-list-thumbnails/150602/1):
>
> By default, Discourse will use the first image in the OP of the topic. If you would like to select a different image from the OP, add `|thumbnail` to the markdown. For example
> 
> ```plaintext
> ![alttext|100x100](upload://aaa)
> ![alttext|100x100|thumbnail](upload://bbb) << this one will be the thumbnail
> 
> ```
