            model.addAttribute("id", imagesObj.getId());
            model.addAttribute("name", imagesObj.getName());byte[] encode =java.util.Base64.getEncoder().encode(imagesObj.getImage());
            model.addAttribute("image",newString(encode,"UTF-8"));return"imagedetails";catch(Exception e)
            logger.error("Error", e);
            model.addAttribute("message","Error in getting image");return"redirect:/";
