Otherwise, load drupal.css and the theme's styles. This still leaves out sites that allow users to use the TinyMCE plugin AND the Add Image link (visibility of this link is now a setting). However, on my site I turned off the text link since I use TinyMCE. I think it would confuse users to have an Add Images link AND a button on the TinyMCE toolbar.
