Basically because you coded an URL link to the page, not an IMG link top the picture file.
shows like https://jimep.imgur.com/all/
for an explanation about these codes.
And if you see a post containing whatever you'd like to do yourself, hit the Quote button as the reply message will then contain the BBCode from that post.
Two quick hits:
Imgur shows 6 or so example links at the side of each photo. One of them contains a complete BBCode link for that picture. You can just copy that and paste it in a post as is.
If you have a picture somewhere on the web and want to share that, then right-click on it and choose Copy image address
, then Edit or Quote a post, put the cursor where you want to insert it, click on the picture icon in the top (the mountains with yellow sky and black sun) and paste it in the URL image address field shown in the popup.
(actually I expect you already knew most of this, but expanded for general info)
