What is a key requirement for images in UD for the web?

Providing short, meaningful alt text for images is a key requirement for ensuring effective understanding and accessibility in web design. Alt text, or alternative text, serves as a crucial descriptor that conveys the content and purpose of an image to individuals who cannot see it, such as those using screen readers. This descriptive text allows users with visual impairments to gain context and information that would otherwise be inaccessible, thereby contributing to a more inclusive online experience.

Utilizing meaningful alt text enhances the overall usability of a website by ensuring that all users, regardless of their abilities, can comprehend and engage with visual content. It is important for alt text to be concise yet informative, balancing the need for clarity with brevity. Providing descriptive alt text also aligns with accessibility guidelines and standards such as the Web Content Accessibility Guidelines (WCAG), which advocate for equitable access to information on the web.
