Embeds images into a post with just an image url.
This plugin parses links that are image urls and changes them into either:
- markdown:
![image-url.jpg](http://images.google.com/image-url.jpg)
- bb code:
[img alt="image.png" title="image.png"]https://images.google.com/image.png[/img]
- html img tags:
<img src="http://images.google.com/image.png" alt="image.png" title="image.png">
