Hi Greg,
Thank you for your reply.
I have tried do add all 9 images and can now see all 4 images but when I click on the picture I can not see larger version (big).
In the admin console there are 4 image fields to upload the pictures. Do I need to upload all 3 pictures for image (image, image_1,image_1_big) in image field 1 and do the same for the remaining set of pictures (image_2, image_2_big in image field 2) etc.
Thank you
