JIT Image Manipulation
------------------------------------

Version: 1.06
Author: Alistair Kearney (alistair@symphony21.com)
Build Date: 10th Aug 2009
Requirements: Symphony 2.0.2 or later

This is a replacement for the /image/X style "just in time" image manipulation found in all versions of Symphony prior 
to v2.0.2

[UPDATE]

Due to some .htaccess changes in Symphony 2.0.6+, it is recommended that you edit your core Symphony .htaccess to remove 
anything
before 'extensions/' in the JIT rewrite. It should look like the following regardless of where you installed Symphony:

  ### IMAGE RULES  
  RewriteRule ^image\/(.+\.(jpg|gif|jpeg|png|bmp))$ extensions/jit_image_manipulation/lib/image.php?param=$1 [L,NC]

It is not absolutely necessary to do this, but may prevent problems with future releases.


[INSTALLATION]

** Note: The latest version can alway be grabbed with "git clone 
git://github.com/pointybeard/jit_image_manipulation.git"

Before you install, it is worth noting that the root .htaccess will be modified. Should you have any modifications, 
it would be worth backing up the original first.

1. Upload the 'jit_image_manipulation' folder in this archive to your Symphony 'extensions' folder.

2. Enable it by selecting the "JIT Image Manipulation", choose Enable from the with-selected menu, then click Apply.

[USAGE]


Basics:

  Image manipulation is controlled via the URL. There are 4 'modes', each with slightly different URL structures
  
  ## TODO: Outline the 4 modes here


Trusted Sites:

  In order pull images from external sources, you must set up a white-list of trusted sites. To do this, 
  goto "System > Preferences" and add rules to the "JIT Image Manipulation" rules textarea. To match anything
  use a single asterisk (*).
