Embeds images into a post with just an image url.
This plugin parses links that are image urls and changes them into either:
- markdown:
 - 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">
