title: Image save doesn't work with chmod 755, but does with 777. What should I do?
body: <p>I have a website where users can crop images. I usually save cropped images under a folder with "755" chmod parameters.</p>
  
  <p>However, when it is 755, it doesn't work - It works when I chmod to 777 and I believe 777 is very insecure so I don't want to use it.</p>
  
  <p>What could be wrong?</p>
  
  <p>Ps. The system works like this. There are some pictures in server, PHP allows user to crop those images and when they click save, it should be saved on /cropped" folder. It works with 777 but not with 755.</p>
