<p><img width="125" height="157" alt="George Washington" 
src="media/gw.jpg"><span>George Washington</span><p>


<p><span>George Washington</span>
<img width="125" height="157" alt="George Washington" src="media/gw.jpg"><p>

Should i repeat <span> in alt in both condition ? image has no link.

Answer 1

Yes.

ALT Text is important for screen readers and such. Text 'nearby' to an image doesn't have much meaning to these programs.

Some more information from W3C on the subject.
