I wasn’t clear, i meant how to set default permissions when i upload files thorough media uploader.Because when i upload files over ftp my files belong to my ftp account, but from media uploader they belong to www user and i cannot change their properties because www owner.How to give less restrictive permissions to files over media uploader.I found this plugin http://ww.wp.xz.cn/plugins/change-uploaded-file-permissions/
but didn’t manage to make him work for my case.Can i edit wpress core file which is responsible for uploading files and set in him default permission like 664 for all uploaded media ??
