You are using the thumbnail modifier on a different image and it’s not working?

@david

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

![alttext|100x100](upload://aaa)
![alttext|100x100|thumbnail](upload://bbb) << this one will be the thumbnail
