I am new to editing code on wordpress by I have basic code knowledge.

I am using this code…

<?php echo do_shortcode(“[metaslider id=235]”); ?>
<?php endif; ?>

Thanks

After updated to version 1.1,
All the thumbnails go upper part and all the post title go lower part.

And there is lu style dot next to each thumbnails.

It would be prefect if the thumbnail is clickable and link to the post.
Thanks !

<?php if (have_posts()) : ?>

		<?php $count=0; while (have_posts()) : the_post(); if(!($firstpost == $post->ID)) : ?>
		<?php if($count % 2 == 0) echo '<div class="left">'; else echo '<div class="right">'; ?>

			<div style="">
				<h2><a href="<?php the_permalink() ?>" rel="bookmark" title="<?php the_title(); ?>"> <?php the_title(); ?> </a></h2>
