# PLUGIN PREVIEW BY TEXTPATTERN.INFO
/**
* smd_thumbnail
*
* A Textpattern CMS plugin for managing multiple image thumbnails:
* -> Create unlimited thumbnail profiles of differing sizes for various site uses
* -> Thumbnail files are created in your image directory -- no realtime scaling
* -> Batch create / alter thumbnails
* -> Choose to sync the thumbnails with Textpattern's own thumbs
*

* TODO: Make Selections (lines 912-916) optional via prefs or something
* TODO: Simplify AJAX response packets to speed things up
* TODO: Interface elements for Profile creation don't get rendered if there are no images in pool
