Как разместить миниатюры слайда справа, столбцом?

Question

[Евгений Шевцов]

Есть вот такой слайдер на css

<div class="slider">
	
	  		<input type="radio" name="slide_switch" id="id1" checked="checked">
	<label for="id1">
		<img src="http://flower.rattlesnake.tmweb.ru/image/cache/data/category-bouquet-medium-2-900x900.png" width="68">
	</label>
	<img src="http://flower.rattlesnake.tmweb.ru/image/cache/data/category-bouquet-medium-2-900x900.png" style="height: 371px;width: 392px;  left: 0px; top: 0px;float: left;">

			<input type="radio" name="slide_switch" id="id2">
	<label for="id2">
		<img src="http://flower.rattlesnake.tmweb.ru/image/cache/data/category-bouquet-big-2-900x900.jpg" width="68">
	</label>
	<img src="http://flower.rattlesnake.tmweb.ru/image/cache/data/category-bouquet-big-2-900x900.jpg" style="height: 371px;width: 392px;  left: 0px; top: 0px;float: left;">

			<input type="radio" name="slide_switch" id="id3">
	<label for="id3">
		<img src="http://flower.rattlesnake.tmweb.ru/image/cache/data/category-bouquet-big-3-900x900.jpg" width="68">
	</label>
	<img src="http://flower.rattlesnake.tmweb.ru/image/cache/data/category-bouquet-big-3-900x900.jpg" style="height: 371px;width: 392px;  left: 0px; top: 0px;float: left;">

	 
	</div>

/*Time for the CSS*/
* {margin: 0; padding: 0;}
body {background: #ccc;}

.slider{
 
	position: relative;
    height: 379px;
 
}


/*Last thing remaining is to add transitions*/
.slider>img{
	position: absolute;
	left: 0; top: 0;
	transition: all 0.5s;
}

.slider input[name='slide_switch'] {
	display: none;
}

.slider label {
	/*Lets add some spacing for the thumbnails*/
	margin: 18px 0 0 18px;
     float: right;
	cursor: pointer;
	transition: all 0.5s;
	    border-bottom: 1px solid #e8e2d1;
	/*Default style = low opacity*/
	opacity: 0.6;
}

.slider label img{
	display: block;
}

/*Time to add the click effects*/
.slider input[name='slide_switch']:checked+label {
 
	opacity: 1;
}
/*Clicking any thumbnail now should change its opacity(style)*/
/*Time to work on the main images*/
.slider input[name='slide_switch'] ~ img {
	opacity: 0;
	transform: scale(1.1);
}
/*That hides all main images at a 110% size
On click the images will be displayed at normal size to complete the effect
*/
.slider input[name='slide_switch']:checked+label+img {
	opacity: 1;
	transform: scale(1);
}
/*Clicking on any thumbnail now should activate the image related to it*/

/*We are done :)*/
