piwigo/include/category_cats.inc.php
rvelices f39bf0bb26 - without subcatify, category thumbnail alt text is 'x images in y sub-categories' 
- improved display of 'x images in y sub-categories' or 'x images in this category' for cases when categories contain both images and sub-categories
- small lang improvement (plural 'Images within the' instead 'Image within the')
