1) is better. For those who know what alt text is, it's already known and  
understood.
2) is  a different pattern, yet does the same thing as (1). It's harder to  
explain, more to understand, requires an id on the <img> which otherwise  
wouldn't need one, and is more to get wrong. It makes a11y harder, and we  
all know that we don't want more impediments.
