I want to display author gravatar on posts. How to do this?

Question

I just want to add author gravatar near the name of the author. I know that I have to add something in the single.php file, but what to add? Thanks!

Answer 1

If you're in the Loop:

echo get_avatar( get_the_author_meta('ID') );

Answer 2

Plenty of info on WP Codex on Gravatar's.

use: get_avatar( "id of author" );
