$q_list['qs'][$index]['content'] = '<a href="/'.$postinfo[$question['raw']['postid']].'" rel="nofollow">'.$image.'</a>';

Or maybe just

$q_list['qs'][$index]['content'] = '<a href="/'.$question['raw']['postid'].'" rel="nofollow">'.$image.'</a>';

Correct syntax errors if any.

It is advisable to use rel="nofollow" tags because the links will redirect to the questions will full urls, and it won't hurt your website crawl budget if Googlebots discover them.

This would probably suffice:

$q_list['qs'][$index]['content'] = '<a href="' . $question['url'] . '">'.$image.'</a>';

Presumably you do want bots to follow links to the actual questions, so "nofollow" would be counter-productive here.

This is a script to display images on question lists. He's already had the question urls in the titles.
$q_list['qs'][$index]['content'] = '<a href="/'.$question['raw']['postid'].'" rel="nofollow">'.$image.'</a>';

This works
Thanks alot....
