Show Custom Image Sizes in Admin Media Uploader

<?php
function show_image_sizes( $sizes ) {
	
	$new_sizes = array();
	
	$added_sizes = get_intermediate_image_sizes();
	
	// $added_sizes is an indexed array, therefore need to convert it
	// to associative array, using $value for $key and $value
	foreach( $added_sizes as $key => $value) {
		$new_sizes[$value] = $value;
	}
	
	// This preserves the labels in $sizes, and merges the two arrays
	$new_sizes = array_merge( $new_sizes, $sizes );
	
	return $new_sizes;
