Why is the image not showing on the right?

Question

WordPress

I do not understand why the picture rises to the left and not to the right? Even though the alignment is right:

<p style="text-align: justify;"><img class="wp-image-167 alignright" style="border: 1px solid black; margin: 10px;" alt="kartinka" src="http://site.com/wp-content/uploads/2013/11/kartinka.jpg" width="384" height="288" /></p>

Answer 1

Here, .alignright obviously does not work for the picture.
If you manually add style="float:right;" for the picture (namely, this should be specified for .alignright as well), everything works as it should.

Answer 2

Since when did justify equate to right?
