 <?php } ?>
 <?php if($_collectionSize){?>
 <div class="jm-products-slider-content clearfix <?php echo $classid; ?>" > 
 <div id="<?php echo $divid?>" class="jm-slider" style="overflow: hidden; width: <?php echo $_collectionSize*($configs['itemwidth']);?>px; float: left; left: 0 !important;"> 
 <ul class="jm-slider-ul">

 <img src="<?php echo $this->helper('catalog/image')->init($_product, 'thumbnail')->resize($configs['width'], $configs['height'])->setWatermarkSize('30x10'); ?>" alt="<?php echo $this->htmlEscape($_product->getName()) ?>"/>
 </a>
 </div> 
 <h5>
 <a title="<?php echo $this->htmlEscape($_product->getName()) ?>" href="<?php echo $_product->getProductUrl() ?>"> 
 
 <?php 
 if (strlen($_product->getName()) > 40) :
 echo strip_tags(mb_substr($_product->getName(), 0, 30, 'UTF-8')).'...';
 else : 
 echo $_product->getName();
 endif;
 ?>
 </a>
 </h5>
 <?php if(is_object($_product->getResource()->getAttribute('author'))) { ?>
 <div class="author">
 <?php echo $_product->getData("author"); ?>
 </div>
 <?php } ?>
 <?php echo $this->getReviewsSummaryHtml($_product, true, true)?>
 
 <?php if ($configs["show_price"]):?>
 <?php echo $this->getPriceHtml($_product,true, '_jmproduct_' . rand()) ?>
 <?php endif;?>
 
 
 
 <?php if(($configs['show_desc']) && ($configs['max'])):?>
 <div class="jm-slider-desc">
 <?php echo mb_substr($_product->getShortDescription(), 0, $configs['max'], 'UTF-8');?>
 </div> 
 <?php endif;?>
 <?php if($configs['show_cart']){ ?>
 <?php if($_product->isSaleable()){ ?>
 <br class="clear" />
 <button class="button" onclick="setLocation('<?php echo $this->getAddToCartUrl($_product) ?>')">
 <span><?php echo $this->helper("catalog")->__('Add to Cart') ?></span>
 </button>
 <?php } else { ?>
 <div class="out-of-stock"><?php echo $this->helper("catalog")->__('Out of stock') ?></div>
 <?php } ?>
 <?php } ?>
 <?php if ($configs['show_readmore']) : ?>
 <a class="product-title" title="<?php echo $this->htmlEscape($_product->getName()) ?>" href="<?php echo $_product->getProductUrl() ?>">
 <?php echo $this->__("Read more") ?>
 </a>
 <?php endif; ?>
 </div>
