I have the following query:

// WP_Query arguments
$args = array (
    'posts_per_page'         => '6',
    'post_type'              => 'attachment',
    'meta_query'             => array(
        array(
            'key'       => 'galeriaimg',
            'value'     => 'sim',
        ),
    ),
);

// The Query
$attachment = new WP_Query( $args );

// The Loop
if ( $attachment->have_posts() ) {
    while ( $attachment->have_posts() ) {
        $img_url = wp_get_attachment_url( $attachment->ID, 'medium', false );
        $img_url_full = wp_get_attachment_url( $attachment->ID, 'large', false );
        echo '<a class="fancybox" href="'.$img_url_full.'">';
        echo '<img src="'.$img_url.'">';
        echo '</a>';
    }
} else {
    echo '<h1>ERRO1</h1>';
}

// Restore original Post Data
wp_reset_postdata();
?>

For some reason, after I added the custom field (meta key) in the query, it stopped returning the images. I already checked the database and the images are related to the meta key, all right, including the value.

What's the problem?

Matheus, apparently the arguments of your query are correct.

If it's still not working, try using a comparison operator on one of the nodes in the meta_query array (and run tests with different operators to see if changes in the behavior of the results occur):

'meta_query'             => array(
    array(
        'key'       => 'galeriaimg',
        'value'     => 'sim',
        'compare    => 'IN',
    ),
),

By default the operator is the "=", which should already result in your expected result .. but test (other available operators in the documentation )
