then, i change 1 image (from this 3) to a newer image and i will give this image the group name "group1". i save the article.
now, when i go to the site on the website and click on a image from this 3, then in popup will show under the image "1 2 3 4".
when i click on this 4 numbers, the new and the old image will show.
can i delete all functions for group name "group1"?
