How do I post pictures?

I only know how to share a link, but I've seen others just post a picture, how do I do that?

 

The easy way: The reply box has an "embed image" button, looks like a picture frame with a couple mountains and a tiny dot/the sun and is right next to the "embed video" button that looks like a strip of film with a play button at the center.
Slightly less easy-way: Use the BBCode [IMG ][ /IMG] (remove the spaces)

Note that it's usually works best if you use the "open image in new tab" function and use the url from the new tab.

 

As TheMidnightRook said, there are two ways. First with the rich text editor. You press the "Insert edit image" button, which brings up a text prompt. You put your direct image URL (a URL ending in an extension like .jpg or .png) in the "Enter image url" field and press "Insert". The image will be added to where your cursor was in the text.





The second way is with BBcode.

Code:

The URL goes between the two tags.

Also you should know how to do spoiler tags as well. A lot of the time it's considered good etiquette to wrap your image in a spoiler tag, especially if it's large, or there are many of them.

Code:

[spoiler=My Avatar][img]https://i.imgur.com/cwJyQ5W.png[/img][/spoiler]

becomes

Spoiler: My Avatar

The text after the equals is the label of the spoiler tag. The content between the two tags is what is hidden.
