<a href="<?php echo $this->item->link; ?>" title="<?php if(!empty($this->item->image_caption)) echo K2HelperUtilities::cleanHtml($this->item->image_caption); else echo K2HelperUtilities::cleanHtml($this->item->title); ?>">
to:
<a class="modal" rel="{handler: 'image'}" href="<?php echo $this->item->imageXLarge; ?>" title="<?php echo JText::_('K2_CLICK_TO_PREVIEW_IMAGE'); ?>">
