Patch submission: get custom image size from system

I noticed the widget does not propose to size the image according to the system’s custom image sizes. In the source code you even complain about it °-)

Well, it was ennoying me too, so i looked around and it turns out there is a global var that contains all that you wish for:

Try echoing this print_r($_wp_additional_image_sizes); to see it for yourself.

so, the patch:

1./ in image-widget.php, add a line at 163:
global $_wp_additional_image_sizes;

2./ in views/widget-admin.php line 40: remove

$possible_sizes = apply_filters( 'image_size_names_choose', array(
					'full'      => __('Full Size', 'image_widget'),
					'thumbnail' => __('Thumbnail', 'image_widget'),
					'medium'    => __('Medium', 'image_widget'),
					'large'     => __('Large', 'image_widget'),
				) );
				$possible_sizes[self::CUSTOM_IMAGE_SIZE_SLUG] = __('Custom', 'image_widget');

and replace line 50 with:

foreach( $_wp_additional_image_sizes as $size_key => $size_label ) { ?>
					<option value="<?php echo $size_key; ?>"<?php selected( $instance['size'], $size_key ); ?>><?php echo $size_key . ' ('.$size_label['width'].' x '.$size_label['height'].')'; ?></option>
					<?php } ?>

That’s it, it works for me, and hopefully for you and your users too!
