To ja się podepnę i powiem że można samemu łatwo dopisać upload.
W config.js dodajemy np. config.filebrowserUploadUrl='http://127.0.0.1/up.php';
I nasz pliczek up.php:
<?php
// Required: anonymous function reference number as explained above.
$funcNum = $_GET['CKEditorFuncNum'] ;
// Optional: instance name (might be used to load a specific configuration file or anything else).
$CKEditor = $_GET['CKEditor'] ;
// Optional: might be used to provide localized messages.
$langCode = $_GET['langCode'] ;
// Check the $_FILES array and save the file. Assign the correct path to a variable ($url).
$url = 'http://127.0.0.1/pattern.png';
// Usually you will only assign something here if the file could not be uploaded.
$message = '';
echo "<script type='text/javascript'>window.parent.CKEDITOR.tools.callFunction($funcNum, '$url', '$message');</script>"; ?>
Tylko nie wiem czemu js nie działa...
