If i replace the <!-- Item Image --> section with this then the page doesn't load at all

This i s what i have in item.php in the K2 template folder of my Mobile template:

 

            <!-- Item Image -->                                         <?php if($this->item->params->get('itemImage') && !empty($this->item->imageLarge)): ?>                     <!-- Item Image -->                     <div class="itemImageBlock">                         <span class="itemImage">                             <a class="modal" href="<?php echo $this->item->imageLarge; ?>" title="<?php echo JText::_('Click to preview image'); ?>">                                 <img src="<?php echo $this->item->imageLarge; ?>" alt="<?php if(!empty($this->item->image_caption)) echo $this->item->image_caption; else echo $this->item->title; ?>" />                             </a>                         </span>                         <?php if($this->item->params->get('itemImageMainCaption') && !empty($this->item->image_caption)): ?>                         <!-- Image caption -->                         <span class="itemImageCaption"><?php echo $this->item->image_caption; ?></span>                         <?php endif; ?>                         <?php if($this->item->params->get('itemImageMainCredits') && !empty($this->item->image_credits)): ?>                         <!-- Image credits -->                         <span class="itemImageCredits"><?php echo $this->item->image_credits; ?></span>                         <?php endif; ?>                         <div class="clr"></div>                     </div>           <?php endif; ?>                                          </a>                   </span>                   <?php if($this->item->params->get('itemImageMainCaption') && !empty($this->item->image_caption)): ?>                                     <!-- Image caption -->

 

 I notice if change the to say the smallest image the image will be smaller, but when i select a larger image size it doesnt change. I also noticed that if i switch my phone from portrait to landscape and back the image is a little bigger. It almost seems like something is automatically resizing it. i don't know what could be doing it though. Any thoughts, this is the last issue i need to get by before going live.
