This plugin is essentially the same as the advimg plugin, only it also has a tab that features previously uploaded images on their ThriveSmart
Site, as well as a form for users to upload images to their ThriveSmart Site.
Simply copy the jscripts/tiny_mce/plugins/tsimage directory into your TinyMCE plugins directory.
This plugin has also been precompiled to work with the CDN version of TinyMCE by Matthew Moore.
