My idea is then when I share a topic or post to social media that image will come up. That to me helps catch people's eyes when trying to drive traffic to the forum and my wordpress site. Thanks again for the consideration. Apologies if I missed the functionality. I thought maybe it could already exist but haven't seen it when I looked if it does.
There are three ways to add image in topic/post
1. URL embed, just put ab image source URL in post content and it'll replaced to image:

2. Attach image using post editor attachment field. It'll show a link, if you want to show it as an image follow this support topic:

3. We're releasing wpForo Advanced Attachments addon in a few days. This is an advanced file attachment system for forum topics and posts. AJAX powered media uploading and displaying system with user specific media library.
