Show Custom Image Sizes in Admin Media Uploader

Add this to functions.php to show additional sizes in the media uploader. You also need to add additional image sizes.

Code Snippet:

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;
add_filter('image_size_names_choose', 'show_image_sizes', 11, 1);
