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

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'.

Re: [PHP] Help creating an image repository/library.
You can also open a socket and put the files up via ftp. I use this method frequently when I cannot move the uploaded files. use the fopen(ftp://user:[EMAIL PROTECTED]/path/to/images,w;) command to place the files. This doesn't work so well if the file already exists, so you have to delete it first using the socket connection. Like so ... (from user comments at php.net/fopen) $ftp=fsockopen(ftp.your.host,21); echo fgets($ftp,255); fputs($ftp,USER your_username\r\n); echo fgets($ftp,255); fputs($ftp,PASS your_password\r\n); echo fgets($ftp,255); fputs($ftp,DELE file_to_delete.txt\r\n); echo fgets($ftp,255); fputs($ftp,QUIT\r\n); echo fgets($ftp,255); fclose($ftp); Jim PS Sorry about missing the point of your question the first time around ...
