Hi. I want to insert images (banner) between the topic answers.
How do I start? Where can I open my theme files, and in what file do I insert a code/link to a image?
Thanks.
Do you mean inserting images between posts? If so, you should consider plugin outlet connector. The post-bottom outlet is probably what you want.
This is the explanation topic about it.
To find the locations of plugin outlet connectors there is a theme component
I’m sorry, I didn’t understood anything. I created an account on this platform to test and see if I can create an online forum for a few companies. This company “Discourse” should advice the visitors before we create an account that for using a forum here it is necessary developer knowledges.
So you’re saying that I need to program in HTML or whatever language it is, only to put image/banner container between the answers in a topic? And that the users are building and expanding the forum for a company for free?

Sorry, I may not have understood correctly what you mean by between the answers. Can you explain it with pictures?
Discourse is an open source forum project. I think when you need to add something highly customized, you may have to have some programming knowledge.
안녕하세요, tullsman님. 반갑습니다. 
Discourse를 사용하는 데에는 개발자 지식이 필요하지 않습니다. 커스터마이징을 개발할 때만 필요하죠.
@Lhc_fl 님이 말씀하신 대로, Discourse는 오픈 소스입니다.
또한 대부분의 커스터마이징(Customization > Theme, Customization > Theme component, Customization > Plugin)도 공식적인 것들을 포함하여 오픈 소스입니다. 사람들은 보통 자신의 필요에 따라 커스터마이징을 만들거나, 누군가에게 개발을 의뢰합니다(예: Marketplace).
많은 커스터마이징이 Discourse에서 무료로 제공되며, 포럼을 자체 호스팅하는 관리자라면 누구나 이를 사용할 수 있습니다.
Discourse의 호스팅 플랜 중 하나를 이용하고 있다면, 여기에서 설명된 제한 사항이 있습니다: Discourse pricing | Discourse - Civilized Discussion
A ok, I thought it was a normal company selling online forums
No problem, feel free to ask if you have any question, we’re happy to help.
