Images must have alternate text
What is the problem?
The image-alt rule ensures that all <img> elements have alternative text (alt attribute) or are marked as decorative using role="presentation" or role="none".
Impacted Groups
Why is this important?
Screen reader users rely on alternative text to understand the content and purpose of images. Without it, they may miss important information or be unable to navigate the website effectively.
How to solve this issue
To fix this, provide concise and descriptive alternative text for all images that convey their meaning. For decorative images that don't add significant information, use role="presentation" or role="none".
