How can we change the default permissions for files uploaded to our web server?

Question

When a user uploads image files to our website the default permissions result in images which can't be viewed. How can we change default permissions to 755 automatically when for uploaded images?

Answer 1

You need to change the umask for your web server. This StackOverflow question talks about how that is done for Apache (add a umask command to the script(s) that are run to start Apache).
