I usually use the "copy and paste button". 

<img src="url" alt="some_text">

Where "url" is the URL of the location of the image (like http://www.w3schools.com/images/w3logotest2.png) and "some text" are the words to show if the picture doesn't work for somebody.

If you have the WYSIWIG editor (ie. there is a bar at the bottom with things like underline and italics) you need to hit the little HTML button on the far right of that bar and do that.

EDIT: ffs it keeps turning it into html code

EDIT 2: Temporarily turned WYSIWIG on, now it works.

 unfortunately you can't upload a picture from your computer so you have to pick one from the internet or upload on using any website like imgur and use the url of the picture you upload

 you doesn't need to edit the HTML of the post just click the picture icon next to the anchor icon that have a picture and insert the url

 and not only for the look , posting lots of pictures won't allow people who have a very slow internet to access the thread easily
