Using image alternatives for accessibility

In TALER ICH we take care that our conversation remains accessible.

This topic is a reminder that we should use the alt property of image tags to provide a decent screen reader experience for the blind and visually impaired.

There are a number of good A11y resources around, like Quick tip: Using alt text properly - The A11Y Project.

In a nutshell, you need to take into account that the image you post will be ‘read’ in its context: if the image is decorative, an empty alt property is much better than anything; if the image is described in text afterwards, then it’s redundant to reproduce the text in the alt property, etc.
