<?php if( get_post_meta( get_the_ID(), 'minti_embed', true ) == "" ){ ?>

				<div id="work-slider" class="flexslider2">
	    			<ul class="slides">
					<?php global $wpdb, $post;
				    $meta = get_post_meta( get_the_ID( ), 'minti_screenshot', false );
				    if ( !is_array( $meta ) )
				    	$meta = ( array ) $meta;
				    if ( !empty( $meta ) ) {
				    	$meta = implode( ',', $meta );
				    	$images = $wpdb->get_col( "
				    	SELECT ID FROM $wpdb->posts
				    	WHERE post_type = 'attachment'
				    	AND ID IN ( $meta )
				    	ORDER BY menu_order ASC
				    	" );
				    	foreach ( $images as $att ) {
				    		// Get image's source based on size, can be 'thumbnail', 'medium', 'large', 'full' or registed post thumbnails sizes
				    		$src = wp_get_attachment_image_src( $att, 'work-detail' );
				    		$src = $src[0];
				    		// Show image
				    		echo "<li><img src='{$src}' /></li>";
				    	}
				    } ?>
