Also try not to embed images one after the other, wait til chat has moved down a bit otherwise it'll mess stuff up.

  To get the images direct link right click the pic and hit copy adress

For Portrait images use;

<img src="THE IMAGES DIRECT URL GOES HERE" width="240" height="360" >

For landscape Images use;

<img src="THE IMAGES DIRECT URL GOES HERE" width="360" height="240" >

And for Square images use;

<img src="THE IMAGES DIRECT URL GOES HERE" width="240" height="240" >

You can change the width and height but keep it low
