Comment 1 for bug 1530606

The old gallery slideshow system was controlled by a gallery/js/slideshow.js file but the new way it is controlled by bootstrap (I think)

The old way had the arrows outside of the image space - the new way has them over the top of the images, which you can't see if you have a dark/black image.

Also bootstrap carousel allows for adding link circles, which we might want to go with.

eg:

        <ol class="carousel-indicators">
        {foreach from=$images item=image key=k name=images}
            <li data-target="#slideshow{$instanceid}" data-slide-to="{$k}"></li>
        {/foreach}
        </ol>
