I want to deactivate a modal on smaller screens like phones and tablets, while keeping it active on larger screens. I've tried using CSS media queries with `visibility:hidden` and `display:none`, but the results are not what I expected. I believe the onClick function needs to be disabled for smaller screens, but I'm struggling to figure out how to do that. Any suggestions on how to achieve this?

When responding to Iceman's message, consider unbinding the click event from your button based on the device's width, such as on a tablet or mobile device:

if( isMobile() || (screen.width <= 800)) {
            $(#yourbutton).unbind('click');
        }

Additionally, utilize CSS to alter the appearance of the button dynamically according to the width, which can help prevent users from unintentionally clicking on it.

To display the model using Javascript, make sure to verify if the device meets your requirements before revealing it. I've crafted a personalized function inspired by a Stack Overflow post to confirm if the device is a mobile one. Additionally, you can validate if the screen width is within the allowed range.

Update your Javascript with the following:

$(function() {
    $('.pop').on('click', function() {
      $('.imagepreview').attr('src', $(this).find('img').attr('src'));
      if ($(window).width() < 800 || isMobile()){
         // perform alternate action for mobile devices
      } else {
         $('#imagemodal').modal('show');
      }   
    });   
});
function isMobile() {
  var isMobile = false; //initialize as false
  // device detection
  if (/(android|bb\d+|meego).+mobile|avantgo|bada\/|blackberry|blazer|compal|elaine|fennec|hiptop|iemobile|ip(hone|od)|ipad|iris|kindle|Android|Silk|lge |maemo|midp|mmp|netfront|opera m(ob|in)i|palm( os)?|phone|p(ixi|re)\/|pluc...
  return isMobile;
}

Assuming you are utilizing Bootstrap, you have the option to utilize the built-in hide classes such as hidden-xs or visibility classes like visible-lg. Since Bootstrap follows a mobile-first approach, your modal will only be visible on large screen devices, which seems to be suitable for your situation.

<div class="modal fade visible-lg" id="imagemodal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
  ...
</div>

If you prefer a JavaScript solution and are still working within the Bootstrap framework with jQuery, you can use the following script to determine the window width and customize the event handling accordingly.

$(document).ready(function () {
            var $window = $(window);

            function checkWidth() {
                var windowsize = $window.width();
                if (windowsize < 1200) {
                    $(".pop").click(function (event) {
                        event.preventDefault();
                    });
                }

                else {
                    $(function () {
                        $('.pop').on('click', function () {
                            $('.imagepreview').attr('src', $(this).find('img').attr('src'));
                            $('#imagemodal').modal('show');
                        });
                    });
                }
            }

            checkWidth();
            $(window).resize(checkWidth);
        });
