How to Ensure Your Images Are Accessible


As a web designer, it is important not only to create websites that are visually appealing but also to ensure that they are accessible to all users. One essential aspect of accessibility is making sure that images on your website are accessible to users with disabilities. In this article, we will discuss how to ensure your images are accessible.

Why Image Accessibility Is Important

Images are a crucial part of any website as they can help enhance the context of the content being presented. However, not all users might be able to view these images or understand their context. Some users might have visual impairments, while others might use assistive technologies such as screen readers that cannot interpret images on their own. Therefore, it is essential to ensure that your images are accessible to all users, including those with disabilities. By doing so, you can provide a better user experience for all your visitors and ensure that your website is compliant with accessibility regulations. Here are some of the best practices to ensure your images are accessible:

1. Use Descriptive Text Alternatives

One of the best ways to make your images accessible is by using descriptive text alternatives. Text alternatives, also known as alt text, provide a textual description of the image, allowing users with visual impairments or assistive technologies to understand the content of the image. Make sure to use descriptive and concise text that accurately conveys the content and context of the image. Avoid using generic phrases such as "image" or "picture" and instead use specific descriptions such as "a man holding a yellow umbrella."

2. Choose Images Mindfully

When choosing images for your website, it is essential to select them mindfully. Consider the context and relevance of the images and whether they add value to the content being presented. Avoid using images for decorative purposes only, as this might not provide much value to users, including those with disabilities. Additionally, avoid using images that might be triggering or offensive to certain users. Make sure that all images on your website are inclusive and do not discriminate against any user group.

3. Ensure the Contrast Ratio Is Adequate

The contrast ratio of an image refers to the difference in brightness between the foreground and background colors. Ensuring that the contrast ratio is adequate can help users with visual impairments perceive the content of the image more easily. The recommended contrast ratio for images is 3:1, with higher ratios providing better visibility. However, keep in mind that the contrast ratio might vary depending on the image's content and context.

4. Provide Captions or Alternative Descriptions for Complex Images

Some images might be too complex to describe accurately with text alternatives or might require additional context. In these cases, consider providing captions or alternative descriptions that can provide more information about the image. For example, you can provide a caption for an infographic that summarizes the key points of the image or an audio description for a video that describes the visual content for users with visual impairments.

5. Test Your Images for Accessibility

Finally, it is essential to test your images for accessibility regularly. Conducting regular accessibility audits can help you identify any accessibility issues on your website, including image accessibility. There are several tools available that can help test your images for accessibility, such as the Accessibility Evaluation Tool (AInspector) or the WAVE Web Accessibility Evaluation Tool. Make sure to address any issues identified during the audit promptly.


Ensuring that your images are accessible is crucial to providing an inclusive user experience for all your website visitors, regardless of their abilities. By following the best practices outlined in this article, you can create images that are accessible and comply with accessibility regulations. Remember always to test your website's accessibility and make necessary adjustments to ensure that every user has equal access to the content you present. Ultimately, creating an accessible website is not only a legal requirement but also the right thing to do to provide an enjoyable and inclusive experience for everyone.
