how to exclude some image from product gallery on front end

Question

I am getting all the product images programmatically to create a banner slider from all of them, right now it is showing all the images that are uploaded from the admin to the specific product.

<?php $galleryData = $product->getData('media_gallery');
       $galleries = $galleryData['images'];
         $_media = Mage::getBaseUrl('media');
             foreach($galleries as $gal_images){ ?>
                <?php echo $all_I_mages =  $_media.'catalog/product'.$gal_images['file']; ?>
                    <div style="background-image:url(<?php echo $all_I_mages ?>);  background-position: center center;  background-repeat: no-repeat;
background-size: auto auto; background-color: #efefef; " >
                    </div>
             <?php   } ?>

Now i want to exclude some of the images from this array for example i dont want to include "small image" , "thumbnail" , and "base image"

can anyone guide what check i need to apply to solve this issue

Answer 1

you can put check something like that.

  if($_product->getThumbnail() != $gal_images['file'] || $_product->getSmallImage() != $gal_images['file'] || $_product->getBaseImage() != $gal_images['file']): ?>
<?php echo $all_I_mages =  $_media.'catalog/product'.$gal_images['file']; ?>
                    <div style="background-image:url(<?php echo $all_I_mages ?>);  background-position: center center;  background-repeat: no-repeat;
background-size: auto auto; background-color: #efefef; " >
                    </div>
<?php
  endif; ?>
