<?php
//Modified version of wp-mail.php for wordpress. 
//This modification handles SL Postcards, and creates an SLink to the location that you took the snapshot from.
//Extra Special thanks to Mr. Fong for making this all possible.
//Requires Imagemagick to be installed on your server.
//Version 1.0

//@REQUIRE: Remove filter from post.php if you want class in the imag thumbnail. very annoying. need to investigate that.
//comment this out: line 506: //$post_content    = apply_filters('content_save_pre',   $post_content);

//@TODO wp-admin pref pane.
//Max Case Apr 8 2007

//////You will need to modify the below, 
//or create the folders /images/postcards/, and /images/postcards/thumbs/
// define path to where postcard images will be stored (include trailing slash)
define('POSTCARDS_DATA_DIR', $_SERVER['DOCUMENT_ROOT'] .'/images/postcards/');

// define path to where postcard thumbnails will be stored (include trailing slash)
define('POSTCARDS_THUMBNAILS_DATA_DIR', $_SERVER['DOCUMENT_ROOT'] .'/images/postcards/thumbs/');
