Gallery Images - Displaying Additional Fields on Front End for image.html

I was using it in the template that lists out the images. a_list_image.html

<perch:before>
    <hr/>
    <h5><perch:gallery id="albumTitle" /></h5>
        <ul class="clearing-thumbs gallery" data-clearing>
</perch:before>

            <li>
                <a class="gallery-hover" href="<perch:gallery id="large" />">
                    <img 
                    data-caption="<perch:gallery id="imageAlt" />" 
                    src="<perch:gallery id="xsmall" />" 
                    width="<perch:gallery id="xsmall-w" />" 
                    height="<perch:gallery id="xsmall-h" />" 
                    alt="<perch:gallery id="imageAlt" />" 
                    />
                </a>
                        <perch:gallery id="test" />
            </li>

<perch:after>
        </ul>
</perch:after>

It shows the following:

No. When I update the field, save and browse out and then go back in to edit the image - the field is empty.

This might be related to some customisation we have had done to the Gallery App. I'll have to check.

Thanks for you help anyway. :)
