ok, so I figured out what the problem is..

My additional images i keep in the /images/ for and i just upload them as image_name_02.jpg 03.jpg etc etc...

Well, the new additional_images.php is linking my 'extra images' to
/images/large/image_name_02_LRG.jpg

what would I edit to make it link the extra images to just how they are which is
/images/image_name_02.jpg


Thanks in advance!
