How does one do such

You can also use the built-in image button if you don't want to manually code it.

Go to the gif or image, right click on your mouse, click copy image, then right click your mouse again where you want to put the image or gif and click paste.

im assuming you cant do it from your phone then?

(not sure actually but I couldn't resist LOL)

If you're on a mobile device go to your browser's settings and check Desktop Site.

I use ImgBB.com to upload pics and gifs

You can. There are several ways to do it, but just learning the syntax for it is way easier. The fun part is trying to get image links on mobile. Sometimes they don't let you grab the image link, but a script that links to it.
