As for the images: ask someone to quote your post, so they'll show up. If you use img tags, they'll show up in your post once you reach Jr. Member.
He isn't using the img tags in his threads from what I can see. He has a services thread started in 2020 where he didn't even post the correct image url. The posted image begins with "
http://https://". His other thread from 2020 is similar. Just a bunch of image urls without the correct tags. So even when he collects the required activity points, OP still needs to post the images correctly for them to show up on the forum.
