Question

How would I go about calling a function in CKEditor from a SWF file in a plugin dialog that closes the dialog after adding an image to the editor?

Answer 1

var functionNumber = CKEDITOR.tools.addFunction(function(url){
            this.insertHtml('<img src="'+url+'" />');
            CKEDITOR.dialog.getCurrent().click('cancel');
        }, editor);

then send that functionNumber to the SWF to send back with callFunction
