You would go to the copy of templates/tpl_product_info_display.php in your templates folder (creating on if you don't already have on there), then grab the following block of code and move it to wherever you think it would be more appropriately located
PHP Code:
<!--bof Additional Product Images -->
<?php
/**
* display the products additional images
*/
require($template->get_template_dir('/tpl_modules_additional_images.php',DIR_WS_TEMPLATE, $current_page_base,'templates'). '/tpl_modules_additional_images.php'); ?>
<!--eof Additional Product Images -->
