That enables you to use all the fancy BBCodes at the forum's disposal:

[img]link to image[/img]                             // displays the image
[url]link[/url]                                      // transforms the link into a clickable hyperlink
[url=link]Text[/url]                                 // transforms the link into a clickable hyperlink with the chosen Text being displayed instead of the link
[url=link][img]link to image[/img][/url]      
                       // displays an image that leads to the specified hyperlink on click

Looks like this when I use the link of my profile picture:

// displays the image
https://a.ppy.sh/392866_1466700659.jpg // transforms the link into a clickable hyperlink
Text // transforms the link into a clickable hyperlink with the chosen Text being displayed instead of the link
// displays an image that leads to the specified hyperlink on click
