SAFE MODE

Okay, I think this comes up a lot, but I'm confused. I have a script that handles some image uploads give to it by the page before, and up until I started messing around with it, it worked. Now I can't get it to work even when I stick the original that used to work back in there. I get the following error each time I run it:
====================
Warning: copy(): SAFE MODE Restriction in effect. The script whose uid is 970 is not allowed to access owned by uid 0 in /home/virtual/site461/fst/var/www/html/userCenter/insertRentalImages.php on line 6
COULD NOT COPY FILES TO MEMORY!
====================
I check the file that the images are supposed to go to, and they are there, but the error comes up anyway. It's very annoying since I'm building this for a friend, not myself, and they will be utterly confused. Keep in mind that I am a novice, so please try to explain things in simple terms, and don't laugh to hard at my script...
