Re: adjacent multiple image links

Hi Loretta,

We'd like to get the official answer from WCAG working group on this issue.

Our understanding was that CASE 1 and 3 would not meet SC 1.1.1
because H2 technique is not used. If this is not true, we'll have to
revise our criterion.

Could you confirm that the official answer from WCAG working group
would be the same?
