This is one that I’ve been passionately pushing for with the discourse team for quite a while - with some help from an awesome external plugin author, and our very own @yegor211 (who has helped tremendously with most of the custom work on this site), our visually artistic community now has a more visual forum!
Note the “R” logo on the bottom post? That’s the default thumbnail - if you see that, it means you should probably link to a cool image or video in your post. If you already have an image in your post, and it didn’t take it, try just editing the post and re-submitting. Sometimes the image just needs to be refreshed with this new system.
**Notice I said “link to” We’re currently still allowing uploads to the forum, but we’re going to run out of storage space at some point, and I’ll have to increase our capacity again, making the site more expensive to run. One day, maybe I’ll ban it, but for now, we’ve been good about not abusing file uploads - let’s keep it up!
