Thread:Project:Support desk/Images were not displayed

Hello together, I have a problem with my mediawiki 1.17.0 installation herer: http://pic-projekte.de/wiki/

My problem: I can upload images without errors but I can not open the images in the browser and so the images were not displayed in my articles. When i try to adress a image directly (for example: http://www.pic-projekte.de/wiki/images/f/f4/64_39.png) i get this message:

Forbidden You don't have permission to access /wiki/images/f/f4/64_39.png on this server. Apache Server at www.pic-projekte.de Port 80

The folder (and all subfolders including the files) are set to chmod 777. Please help my I am totaly confused :(

Edit: a) I guess I have Mysql: 5.0.84 an PHP: 5.2.17 b) The problem (or the error message) is also there when I try to run the update.php after i added an extension
