RE: [PHP] Help creating an image repository/library.

You don't want to store the files in the root public directory. Create a subdirectory for uploads, 'public-html/uploads' for example. Make sure it's permissions are 755. From the command line, 'chown nobody,nobody uploads' would do it. The syntax for chown is 'chown <user>,<group> <file/directory>'.

That would be an ideal solution. But one of my problems is that I'm not very familiar with permission settings. All I know about is CHMOD. What exactly is CHOWN and how would I set it to allow the script upload to a public directory without risking the security of the web site?
