Post thumbnails are enabled in the twenty-eleven theme by default. If it’s not working either you have a plugin conflict, or someone has edited the functions.php file. Here is the section of the twenty-eleven functions.php file that should enable the post thumbnails:
add_theme_support( 'post-thumbnails' );
The code needs to be inside the function twentyeleven_setup() function to work.
