I made a CMS on which my boss could edit his text online. Now I want him to be able to add, delete or change the existing image on the website by using a WYSIWYG functionality. Something like he would choose the page where the image he wants to edit is integrated, display the html page, and add, replace or delet it according to his will. Right now, I don't have any idea how to do that. I'll really appreciate any kind help.
