php - NicEdit upload on your own server

i have problem with uploading on my own server with nicEdit wysiwyg editor.

When you clikc on upload image you will upload image on other site. Here: imgur dot com

This is it: http://nicedit.com/demos.php

I want to use them php script to upload image on my own server/domain. Can somebody tell me how to do it?

Here is the script: http://svn.nicedit.com//trunk/nicUpload/php/nicUpload.php

Still show message "Failed to upload image".

In console on firebug show this one:

<script>
        try {
            top.nicUploadButton.statusCb({"error":"Invalid Upload ID"});
        } catch(e) { alert(e.message); }

</script>
Copy code

POST is okay but i dont understand this. :(

Have anybody som good answer for me?

Thank you very buch. PS: sorry for my english. :)

Daniel.
