[1] Wouldn't this markup work? <img src="chart.png" alt="..." aria-describedby="chart-description"> <p hidden id="chart-description"> long description here. </p> Note that the 'hidden' attribute prevents the description from being displayed inline, but doesn't prevent it from being exposed to AT users. You can even support older UAs which doesn't support the 'hidden' attribute using CSS or simply adding a style="display:none;" attribute. This seems to work in firefox based on code inspection, though wouldn't mind getting it confirmed by someone with AT tools installed. / Jonas
