            // Get the filename and extension
            var fileName = Path.GetFileName(imageFile.FileName);
            var fileExtension = Path.GetExtension(fileName);

            // Generate a unique filename (you can use other methods for generating unique names)
            var uniqueFileName = Guid.NewGuid().ToString() + fileExtension;

            // Save the file to the server (you can change the path to where you want to store images)
            var imagePath = Path.Combine(Server.MapPath("~/Uploads/"), uniqueFileName);
            imageFile.SaveAs(imagePath);

            // Here, you can perform any additional processing with the image if needed.

            // Return a success response
            return Json(new { success = true });
        }

        // If the image is not provided or has no content, return an error response
        return Json(new { success = false });
    }
}
