Custom Image Size (WordPress)

custom-image-size.php

<?php
//* Do NOT include the opening php tag shown above. Copy the code shown below.

//* Add new custom image sizes
add_image_size( 'image-name', 150, 100, TRUE );

/* DO NOT include the following it is for instructional purpose only
 * 
 * Replace 'image-name' with the descriptive name you want to identify the new image size with. 
 *    DO NOT use thumb, thumbnail, medium, large, or post-thumbnail
 * The next two numbers are the width and height of the image in pixels respectively. 
 * The final TRUE/FALSE is in response to assumed question "Should this image be cropped to these dimensions". If true it will be cropped.
 *    If false the image will be scaled, not cropped (not recommended). If true can also specify where to crop in the form of an array. 
 *    x_crop_position accepts 'left', 'center', or 'right' and y_crop_position accepts 'top', 'center', or 'bottom'
 *        ex. add_image_size( 'custom-size', 220, 200, array( 'left', 'top' ) ); // hard crops the top left 220x200 of image
