This is a tiny CKEditor to upload files insinde your editor.

Move the plugin folder inside your CKEditor plugins folder and enable it in your config.js by adding uploadFile to config.extraPlugins

Available configurations are:

uploadFile: {
    accept: '.png,.jpg,.jpeg,.gif,.pdf', // Allowed extensions, * to allow all files
    maxFileSize: 0, // Maximum size in bytes
    uploadHandler: 'URL', // URL to the file upload handler (to where submit the file)
    inputName: 'file', // File name (input name)
    extraFormData: { // Any extra form data that should be sent with the request
        'name': 'value',
    },
},

The upload handler must return a JSON response containing the URL to the file and a 200 status header. If you want to pass an error message, you need to set the status header to 500 (or any other error header) and pass the message along the header, for example in PHP:

header('Status: 500 The file you uploaded is too big');
