Thread:Project:Support desk/Problem with thumbnail subfolders chmods

Hi, I had a problem with automatic creation of thumbnails on my wiki. After some investigating I discovered that subfolders (created in .../images/thumb) for thumbnails after image upload suprisingly don't want to inherit chmods of parent folder (775) and have 744 chmod instead. Of course after changing chmods by hand, thumbnailing works great, but this is a little exhausing. I couldn't find any tips for this problem on FAQ/whole site/whole net - or maybe I couldn't understand them, because of my poor English or even poorer computer skills ;-) So, how can I 'convince' them to inherit those chmods properly? I would be deeply grateful for help on this :-)

My versions are: MediaWiki - 1.16.2, PHP - 5.2.4 (cgi-fcgi) MySQL - 4.0.27-log. I dont have the direct access to the advanced (?) server functionalities (such as modyfing php.ini etc.), but if it's necessary, it can be done.
