An image carousel lets you display multiple pictures in a row or a loop, with several navigational options, including automated timed cycling, forward and back buttons, thumbnails, pagination, and swipe capabilities in mobile view. Commonly, they accommodate between three to five images, though some can host more.
Carousels can simultaneously display different types of information visually, reducing the need to navigate to multiple pages or scroll endlessly. They're a perfect feature for e-commerce platforms, news and blog sites, portfolio pages, and more, as they bring a dynamic element to any web page design.
However, poorly planned or overused, they may hurt your website's usability and SEO, thereby negatively affecting user engagement and conversions. Thus, a measured and strategic approach is advised while employing image carousels.
