Which technique should be implemented to make pages more accessible for users with slower Internet connections?

The correct choice, image interlacing, enhances the experience for users with slower internet connections by allowing them to see a version of the image before it is fully loaded. Interlacing works by loading a low-resolution version of the image first, which gives users a quick preview. As the data continues to load, the image gradually sharpens into a clearer version. This technique is particularly beneficial for users on slow connections because it provides them with visual feedback immediately, rather than forcing them to wait for the entire image to load before seeing anything.

This approach not only improves the perceived speed of the web page but also enhances overall user experience, as users can begin to assess the page content without waiting for all resources to be fully loaded. Implementing image interlacing is thus a strategic way to accommodate the needs of users with varying bandwidth capabilities.
