My solution to this problem is as // follows: // If this image assist window was loaded from TinyMCE, then include the // TinyMCE popups_css file (configurable with the initialization string on the // page that loaded TinyMCE). 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. // // Note that in both cases the img_assist.css file is loaded last.
