I have stored all the images in server root directory Ex: "/mnt/image/pic.jpg" now i want to view this image in browser,but normally can access only inside /var/www/... how to achieve this.
Link the directories
ln -s /mnt/images /var/www/images
After that you can access to /var/www/images/pic1.jpg without any problem (check user and group permissions if you cannot access)
EDITED with @Anders advice
Don't forget to add Options FollowSymLinks
if you are using Apache web server
