I’d show pictures, but I’m not sure how to post pictures here yet.
When using the Visual post editor, you should see a picture button on the far right that requires the url source. For the sake of forum speed and potential quoting/unresolved site issues (sorry, hope to resolve sometime!), I’d prefer if people didn’t post a ton of pictures within their posts. But you can also link to the picture as you would a regular link that should open in a new tab, same for albums.
