I created a plugin and I need to use add_image_size in it.
I know how it works in the functions.php file and for a theme, but how can I implement this in a plugin?
I want new images uploaded by WordPress users to be smaller for mobile screens by
add_image_size( 'wp_small', 60, 75, true ); // mobile
I read that you need to use init or admin_init but I don't know how to implement this.

- Did you finish your plugin yet? And did you release it by any chance? I'm searching for one currently, can't be bothered to code something... :D – Julian F. Weinert Commented Feb 8, 2021 at 13:00

Reset to default 6Just call this function in the init action. This action is fired for both frontend and backend. So it should look like this:
add_action( 'init', 'wpse4378_add_new_image_size' );
function wpse4378_add_new_image_size() {
add_image_size( 'wp_small', 60, 75, true ); //mobile
}
It's better to call it in after_setup_theme instead of init action:
Codex says you should call add_image_size in functions.php so the closest action is after_setup_theme. Then you have:
add_action( 'after_setup_theme', 'your_theme_setup' );
function your_theme_setup() {
add_image_size( 'wp_small', 60, 75, true ); //mobile
}
