I have a problem inserting new images in the Home slider of my site. My site is www.inoksanitalia.it , with the Porto theme. I’ve already tried adding them from the System-> Configuration-> Home slider section but it only gives me 2 attributes to edit. If I go to insert the image in the directory of the slider and I insert another line in the file for home-slider.phtml it shows me only the two images already inserted and not the third one. How can I insert them, if ever easily from the Magento backend?
