Using system call + wrapper?

Hi

I am trying to allow people to save images from their file system to a
directory on my machine called images, for example the path that I want to
save to is /usr/local/apache/htdocs/project/images/.

Obviously from above I am using an Apache web server, PHP and PostgreSQL.
My problem is that you need sudo access to save anything to this
directory so I get a "Permission denied..." error on the browser. I want
to save the image to the images directory and save the path to a table in
my database, however I can do neither in the current situation.

It was suggested to me to use a wrapper that invokes a system call such as
system('sudo upload.php -p password') that will run the program in sudo
but I really don't know where to start with this??

Can anyone please help me?
