Why are client-side image maps more common than server-side image maps?

Client-side image maps are indeed more common than server-side image maps primarily because they are easier to implement. With client-side image maps, you can define clickable areas directly within the HTML using the <map> and <area> tags. This method allows for immediate interaction without the need for additional server-side processing, which contributes to faster load times and a more seamless user experience.

In contrast, server-side image maps necessitate the use of CGI scripts to process the clicks on the image, requiring a more complex setup. This involves additional steps, such as sending a request to the server every time an area on the image is clicked, which can introduce increased latency and complexity in implementation and debugging. As a result, client-side image maps not only streamline the development process but also improve the overall performance of web pages.

The advantages of client-side image maps regarding ease of use and implementation contribute significantly to their prevalence in web development, making them a preferred choice for developers looking to enhance interactivity with minimal overhead.
