# Fix TimThumb
# The following will replace any versions of timthumb.php or thumb.php across your server. 
# Change the folder to match your server's setup.
# If you have made any modifications, or have any additional allowed hosts in your current 
# TimThumb file they will be updated, so make sure you have those changes backed up.
