Captions on right side of image

Hi all,

I’m working on a child theme of twenty twelve where I would like the image caption to appear to the right of actual image. I’ve been looking at other older blog posts including this one:

The code I got from there is this (put in functions.php of child theme) but is two years old, so maybe things need to be changed(?):

/*
 * move captions to right of image
 */
add_shortcode('wp_caption', 'fixed_img_caption_shortcode');
add_shortcode('caption', 'fixed_img_caption_shortcode');
function fixed_img_caption_shortcode($attr, $content = null) {
	// Allow plugins/themes to override the default caption template.
	$output = apply_filters('img_caption_shortcode', '', $attr, $content);
	if ( $output != '' ) return $output;
	extract(shortcode_atts(array(
		'id'=> '',
		'align'	=> 'alignnone',
		'width'	=> '',
		'caption' => ''), $attr));
	if ( 1 > (int) $width || empty($caption) )
	return $content;
	if ( $id ) $id = 'id="' . esc_attr($id) . '" ';
	return '<div ' . $id . 'class="wp-caption ' . esc_attr($align)
	. '" style="width: ' . ((int) $width+ 299 + 20) . 'px"><span style="float:left;">'
	. do_shortcode( $content )
	. '</span><p style="float:right; width: 301px;" class="wp-caption-text">'
	. $caption
	. '</p><span style="float:none;clear:both;display:block;"></span></div>';
	}

It partly works… the image caption moves to the right of the image but all styling is removed and it aligns at the baseline of the image. I would like the caption to align to the top of the image so that the text fits nicely beside the image. Here is the link to the page:

I am new to wordpress, so I apologize if the fix is logical. Thank you for your help!
