Tinymce - pridani pluginu

Dobry den, mam problem s pridanim pluginu do wysiwyg editoru tinymce (http://tinymce.moxiecode.com/index.php). jedna se konkretne o tento plugin:
http://sourceforge.net/tracker/index.php?func=detail&aid=1594246&group_id=103281&atid=738747.
podle redadme bych mel postupovat nasledovne:
1. Copy the iwimg folder to your tinyMCE plugins directory.
2. Create a folder to store your images in (chmod 777/755). I usually call this "wysiwyg_images" and put it in the same location as the website.
3. Create a mysql database and run image.sql (in INSTALL FILES folder) to create the tables with demo data.
4. Open conf.inc.php and change the variables for your setup.
5. Add the plugin "iwimg" to list of plugins and on a button row in your tinyMCE init code.
6. A "thumbs" and "originals" folder 'should' be created automatically on upload of your first file under your image path. If you get errors, and they aren't there, create them manually (755/777).
zasekl jsem se na bodu 5. moc jsem nepochopil kam mam plugin zapsat a jak jej zprovoznit =o/ nemate s tim nekdo zkusenosti prosim?

aha, tak kam to vlozit jsem uz pochopil.. ma se to vozit do hlavicky stranky za: "tinyMCE.init({ (kod dal pokracuje.....)" mezi pluginy... tak to jsem presne udelal a bohuzel mi to jaksi nefunguje.. plugin se nezobrazi =o/

aha, koukam je potreba GD knihovna... mam na localhoste nainstlovany XAMPP nejnovejsi verzi pro Windows, a vypada to ze ta GD knihovnu neobsahuje... je to pravda? je mozne ze kvuli tomu to nejde? :)
