By default, FCKEditor textarea uses the same background image as your theme in Drupal. To remove the background image from the FCKEditor use default black text on white background so that it is easy to read/write inside the editable area, go to Edit FCKeditor profile (do this for all the profiles that you wish to change), Home › Administer › Site configuration › FCKeditor settings and under Editor CSS section, choose FckEditor default.
