main and additional images modal

[keneso]

Hi

Using 1.55

I have changed MY_TEMPLATE/templates/tpl_modules_main_product_image.php so that instead of the js popup it opens in a modal, and works fine.

I would like to do the same with the additional images as well, and possibly in the same modal, so to have "next"/"previous" buttons.

The code for main image is

<div id="productMainImage" class="centeredContent back">
    <div type="button" class="btn btn-lg fz-product-image" data-toggle="modal" data-target="#fz-modal">
    <?php
    echo zen_image($products_image_medium, $products_name, LARGE_IMAGE_WIDTH, LARGE_IMAGE_HEIGHT) . '<br /><span class="imgLink">' . TEXT_CLICK_TO_ENLARGE . '</span></a>';
    ?>
    </div>
</div>
    <!-- start modal window -->
    <div class="modal fade" id="fz-modal" tabindex="-1" role="dialog" aria-labelledby="fz-modal-label">
        <div class="modal-dialog" role="document">
            <div class="modal-content">
                <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
                <h4 class="modal-title" id="fz-modal-label">
                <?php echo $products_name; ?>
                </h4>
                </div>
                <div class="modal-body">
                <?php
                echo zen_image($products_image_large, $products_name, LARGE_IMAGE_WIDTH, LARGE_IMAGE_HEIGHT);
                ?>
                </div>
                <div class="modal-footer">
                <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
                </div>
            </div>
        </div>
    </div>
    <!-- END modal window -->

I played with includes/modules/MY_TEMPLATE/additional_images.php and managed to trigger the modal, but the image loaded would be the small main one, and not the additional one/s, and obviously not "next"/"previous" buttons; as you can guess I basically copied the main image code, and put it in the additional one, commenting out the script part ($script_link)

I just can't interpret all the php, I kinda can imagine some of it what it does, but putting it together to do what I need is just over me.

Thank you.
