Usually it autodetects them when you paste them in. I prefer using imgur than tinypic too.

You can also do it like this; https://i.gyazo.com/c5a05c59ab38518574755b82005a1802.mp4

upload to imgur

then, use the right click the image, "copy image address", then paste within links. so like imgur.com/23123814kfdkfk[/img

you can even just straight up copy and paste the image if that tickles your fancy
