thats the thing, i havent got the global additional tabs set to on. ive toggled between on and off and it still shows inside the tabs. i havent added it as a tag in the description either. in " includes/templates/example_template/templates/template_product_info_display.php however, there is this code "<!--bof Additional Product Images -->
<?php if (!$bAdditionalImages && !$bsubtab_AdditionalImages) {
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 -->

i dont know whether this is affecting it. i removed it however temporarily and the tab was still there.... there seems to be no way to get rid of it!!
