Upload Button doesn't show on WP 3.5.2

I’m having the same problem on WP 3.6.

Looks like the dev has forgotten about the plugin. This is an easy fix though. Just have to change one line in the plugin’s php file.

Changed line 369
from
echo _media_button(__('Add an Image'), 'images/media-button-image.gif?ver=20100531', 'image',$scwp_plugin_name);
to
echo media_buttons(__('Add an Image'), 'images/media-button-image.gif?ver=20100531', 'image',$scwp_plugin_name);
