Decorative images — icons, dividers, background graphics — should not have alt text. Screen readers skip them when alt="" is present, per W3C WCAG guidelines. The web snippet provides two ways to skip images.

​
Skip individual images

Add either a CSS class or a data attribute to the <img> tag. CSS class: 
<img class="icon atlab-ignore" src="icon.svg" />
Data attribute: 
<img class="icon" src="icon.svg" data-atlab-ignore />
Both methods prevent generation. If alt text was previously generated for the image, it will not be applied.

​
Skip images by size

By default all images are processed regardless of size. To skip small images, set the data-min-natural-size parameter on the snippet script tag to a positive pixel value: 
data-min-natural-size="100"
See Installation & configuration for the full parameter reference.
