Impact听
When adding images to digital content, it鈥檚 important to think about both users who can view visuals and those who cannot. This includes individuals who are blind or have low vision, as well as anyone using assistive technology or browsing with images turned off. Without alternative text, those users miss out on the information conveyed by images. The message behind the image is lost unless it鈥檚 described in text.听
