可以通过JavaScript来实现动态更换背景图片。你可以通过获取要更换的背景图片的URL，并将其设置为元素的background-image样式来实现。下面是一个简单的示例代码：

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Dynamic Background Image</title>
<style>
    body {
        background-image: url('original-background.jpg');
        background-size: cover;
        background-repeat: no-repeat;
        height: 100vh;
        margin: 0;
        display: flex;
        justify-content: center;
        align-items: center;
    }
</style>
</head>
<body>
    <button onclick="changeBackground()">Change Background</button>
    <script>
        function changeBackground() {
            const newBackgroundUrl = 'new-background.jpg';
            document.body.style.backgroundImage = `url(${newBackgroundUrl})`;
        }
    </script>
</body>
</html>
