Colorblind users benefit when all content, including images, uses generous color contrast ratios. When magnified, images can appear pixelated and hard to understand. Users with low vision often magnify the page. They can find moving, flashing, or automatically animating images (including gifs) problematic. Users with cognitive impairments, motion sensitivity, or seizure disorders may not tolerate some kinds of images well. In both cases, the browser will show the image’s alt text. Likewise, images may not load when a user has a slow internet connection. Users with cognitive impairments may prefer to disable images from loading. Text alternatives are also important when images do not load. When a screen reader encounters an image, it will attempt to read a text alternative. Pages should provide effective text alternatives for screen readers in the form of alt text. Screen reader users include people who are blind, have low vision, or have cognitive disabilities.
