Let's try now to remove an  image from the list of images. Click on the icon right here; it shows an  error in red "Used figure" which means you   can't remove it because it's already  assigned to a question or a response. To avoid this situation, first, dissociate  the image from the question by selecting   "none", save changes, try again  to remove the image, DONE! The image is now removed because it is  not assigned to any question or response. The same logic goes for removing formulas images;  if it's already assigned, it will show an error. Dissociate it from any element  using it, a question or a response,   and it'll be removed.
