SUMMARY

- Changed img_config.php variables to UPPERCASE to emphasize that they came from a config file
- Added new Thumbnail feature. Avatars can now be displayed using smaller thumbnails.
  You can see this with thumb_nail.php in avatars.
  The Thumbnail will only appear at the bottom of index.php for now.
- Created a helper folder with imgHelpers. The helper folder is for FUNCTIONS OR OTHER HELPFUL CODE that will serve only as
   auxiliary code at the beginning of a PHP file.
DATABASE CHANGE

-The Database has been changed. There will be a table called "user_avatar" with tables: "username varchar(16)" "pathname varchar(260)" "thumb_pathname varchar(260)." The pathnames represent the pathnames to the original profile picture and the thumb nail picture respectively.

WHAT YOU NEED TO CHANGE

Do we really need $url_root anymore. I'm starting to use absolute pathnames to refer to resources now (e.g /avatar/create_avatar.php)
SUMMARY

-Changed some relative pathnames to absolute pathnames
-Added $_SESSION['thumb_avatar'] for thumb_nail pathname storage in session.
-Various other deletions from code
