Hola. Yo también estoy usando ese editor en un proyecto que acabo de empezar y me funciona de maravilla.
Te comento lo que hice yo para quitar la opción del browser. Es muy sencilla.
En la raíz del directorio donde tienes el editor, hay un archivo que se llama fckconfig.js
Desde la linea 284 hasta la linea 325 aproximadamente tiene estas lineas:
Código:
FCKConfig.LinkBrowser = true ;
FCKConfig.LinkBrowserURL = FCKConfig.BasePath + 'filemanager/browser/default/browser.html?Connector=' + encodeURIComponent( FCKConfig.BasePath + 'filemanager/connectors/' + _FileBrowserLanguage + '/connector.' + _FileBrowserExtension ) ;
FCKConfig.LinkBrowserWindowWidth = FCKConfig.ScreenWidth * 0.7 ; // 70%
FCKConfig.LinkBrowserWindowHeight = FCKConfig.ScreenHeight * 0.7 ; // 70%
FCKConfig.ImageBrowser = true ;
FCKConfig.ImageBrowserURL = FCKConfig.BasePath + 'filemanager/browser/default/browser.html?Type=Image&Connector=' + encodeURIComponent( FCKConfig.BasePath + 'filemanager/connectors/' + _FileBrowserLanguage + '/connector.' + _FileBrowserExtension ) ;
FCKConfig.ImageBrowserWindowWidth = FCKConfig.ScreenWidth * 0.7 ; // 70% ;
FCKConfig.ImageBrowserWindowHeight = FCKConfig.ScreenHeight * 0.7 ; // 70% ;
FCKConfig.FlashBrowser = true ;
FCKConfig.FlashBrowserURL = FCKConfig.BasePath + 'filemanager/browser/default/browser.html?Type=Flash&Connector=' + encodeURIComponent( FCKConfig.BasePath + 'filemanager/connectors/' + _FileBrowserLanguage + '/connector.' + _FileBrowserExtension ) ;
FCKConfig.FlashBrowserWindowWidth = FCKConfig.ScreenWidth * 0.7 ; //70% ;
FCKConfig.FlashBrowserWindowHeight = FCKConfig.ScreenHeight * 0.7 ; //70% ;
FCKConfig.LinkUpload = true ;
FCKConfig.LinkUploadURL = FCKConfig.BasePath + 'filemanager/connectors/' + _QuickUploadLanguage + '/upload.' + _QuickUploadExtension ;
FCKConfig.LinkUploadAllowedExtensions = ".(7z|aiff|asf|avi|bmp|csv|doc|fla|flv|gif|gz|gzip|jpeg|jpg|mid|mov|mp3|mp4|mpc|mpeg|mpg|ods|odt|pdf|png|ppt|pxd|qt|ram|rar|rm|rmi|rmvb|rtf|sdc|sitd|swf|sxc|sxw|tar|tgz|tif|tiff|txt|vsd|wav|wma|wmv|xls|xml|zip)$" ; // empty for all
FCKConfig.LinkUploadDeniedExtensions = "" ; // empty for no one
FCKConfig.ImageUpload = true ;
FCKConfig.ImageUploadURL = FCKConfig.BasePath + 'filemanager/connectors/' + _QuickUploadLanguage + '/upload.' + _QuickUploadExtension + '?Type=Image' ;
FCKConfig.ImageUploadAllowedExtensions = ".(jpg|gif|jpeg|png|bmp)$" ; // empty for all
FCKConfig.ImageUploadDeniedExtensions = "" ; // empty for no one
FCKConfig.FlashUpload = true ;
FCKConfig.FlashUploadURL = FCKConfig.BasePath + 'filemanager/connectors/' + _QuickUploadLanguage + '/upload.' + _QuickUploadExtension + '?Type=Flash' ;
FCKConfig.FlashUploadAllowedExtensions = ".(swf|flv)$" ; // empty for all
FCKConfig.FlashUploadDeniedExtensions = "" ; // empty for no one
FCKConfig.SmileyPath = FCKConfig.BasePath + 'images/smiley/msn/' ;
FCKConfig.SmileyImages = ['regular_smile.gif','sad_smile.gif','wink_smile.gif','teeth_smile.gif','confused_smile.gif','tounge_smile.gif','embaressed_smile.gif','omg_smile.gif','whatchutalkingabout_smile.gif','angry_smile.gif','angel_smile.gif','shades_smile.gif','devil_smile.gif','cry_smile.gif','lightbulb.gif','thumbs_down.gif','thumbs_up.gif','heart.gif','broken_heart.gif','kiss.gif','envelope.gif'] ;
FCKConfig.SmileyColumns = 8 ;
FCKConfig.SmileyWindowWidth = 320 ;
FCKConfig.SmileyWindowHeight = 210 ;
FCKConfig.BackgroundBlockerColor = '#ffffff' ;
FCKConfig.BackgroundBlockerOpacity = 0.50 ;
FCKConfig.MsWebBrowserControlCompat = true ;
FCKConfig.PreventSubmitHandler = true ;
Es tan fácil como poner a false todos los trues que hay marcados. y así desaparece la opción de subir archivos en el fck.
Espero que te sirva de algo. Saludos y suerte con el proyecto
