This adds a shortcodes drop down on the Wordpress TinyMCE editor.
I needed an array of shorcodes that would be replaced by images. I've got it working and I know it isn't the optimal code and that it came from a tutorial. But hey, I'm not a programmer so relax. ¯_(ツ)_/¯
The original tutorial can be found here: http://code.tutsplus.com/tutorials/guide-to-creating-your-own-wordpress-editor-buttons--wp-30182
You will see loads of coding errors so please be nice :) I can include your suggested changes to the code. If it doesn't break it of course :)
So if you wan't to contribute, I'll be very happy to see the outcome of this.
Many thanks
Changed the way the plugin relates to the path of the images.
