i trying write query user_id , associated image displayed.

ex. user_id:1 - image 55052a098c146.jpg, imagename.jpg ex. user_id:2 - image 55052a098c146.jpg, imagename.jpg

and soon.

can done in 1 select query.

i checked following, of no help. https://wpbits.wordpress.com/2007/08/08/a-look-inside-the-wordpress-database/

you're doing wrong. shouldn't query wordpress database directly, use wp functions instead, get_posts or wp_query class, depends of need. functions handle taxonomy / meta queries you.

some reading : https://wordpress.stackexchange.com/questions/1753/when-should-you-use-wp-query-vs-query-posts-vs-get-posts

the case when should use wpdb class query database directly when you're working custom tables.

so, in case, assuming want profile picture, can use get_avatar function:

echo get_avatar(1) // display profile picture of user id 1
