Images play a powerful role in online content, conveying messages, enhancing design, and driving engagement. However, they also present accessibility challenges for users who rely on assistive technologies like screen readers. To ensure inclusivity, websites must optimize images using **ALT Text** and **Long Descriptions**. This not only benefits people with visual impairments but also enhances search engine optimization (SEO) and ensures compliance with legal requirements like Title II of the Americans with Disabilities Act (ADA).
The Purpose of ALT Text
- ALT Text: The Quick Summary
ALT Text (alternative text) is a short textual description of an image. Its primary purpose is to convey the image’s essential function or content for those who cannot see it. Screen readers read ALT Text aloud, allowing users to understand the image’s purpose within the context of the webpage. - Key Uses of ALT Text
-Provide a concise description of the image.
-Serve as a placeholder when images fail to load.
-Improve SEO by including relevant keywords (only when appropriate). - Example of ALT Text
For an image of a shopping cart icon, the ALT Text could simply be: *“Shopping cart icon for online checkout.”*
The Purpose of Long Descriptions
Long Descriptions are extended explanations used for complex images such as graphs, infographics, or detailed illustrations. Unlike ALT Text, they can be lengthy and are typically provided as a separate piece of text linked or embedded near the image.
- Key Uses of Long Descriptions
-Explain intricate visuals that cannot be adequately described in ALT Text.
-Provide full context for educational or technical images.
-Support users who rely on detailed descriptions for comprehension. - Example of Long Description
For a graph showing quarterly sales performance, a long description would detail the x- and y-axes, the trends shown, and the significance of the data.
Understanding Title II ADA Image Requirements for Web Accessibility
Title II of the ADA mandates that public entities (like government agencies) and businesses offering public accommodations ensure their websites are accessible to all, including individuals with disabilities. While the ADA doesn’t provide specific technical guidelines, the Web Content Accessibility Guidelines (WCAG) are widely accepted as the standard for compliance.
Image Accessibility Requirements Under WCAG
- ALT Text: All informative images must have ALT Text.
- Decorative Images: These should use empty ALT attributes (`alt=””`) so screen readers ignore them.
- Complex Images: Provide long descriptions for charts, maps, or infographics.
- Responsive Images: Ensure ALT Text adapts across devices and platforms.
Failing to meet these requirements can result in legal penalties and limit access for millions of potential users.
Why Businesses Must Optimize Images for Accessibility
- Legal Compliance: ADA lawsuits are increasingly targeting inaccessible websites. Ensuring images are properly optimized can protect your business from costly litigation.
- Improved User Experience: Accessible images enhance usability for all users, especially those with visual impairments.
- SEO Benefits: Search engines use ALT Text to understand image content, boosting your site’s ranking.
- Inclusive Branding: Demonstrating a commitment to accessibility improves public perception and expands your audience reach.
