I succeeded to add the image and file upload buttons to my rich text redactor field with the fileupload param in the json config file.
{
buttons: ['html','formatting','bold','italic','unorderedlist','orderedlist','link','image','video','table','file'],
plugins: ['fullscreen','video','table',''],
toolbarFixed: true,
fileUpload: 'fichiers/'
}
But it does not work : when I drap and drop a file or an image it shows the top bar indicating upload in progress but it finish without anything inserted in my field.
