thanks for your answer !
you mean using $baz to display the categories ?
I'm not sure I see how to do... but I'll search in that direction
<?php
$args=array(
'taxonomy' => 'marque',
'orderby' => 'name',
'order' => 'ASC'
);
$baz=get_categories($args);
foreach($baz as $category) {
echo '<div id="marque1">'
echo '<h1><a href=" ' . get_category_link( $category->term_id ) . ' " ' . '>' . $category->name.'</a> </h1> ';
echo '<img src=" '. $category->image . ' " ' . ' />;
echo '</div>'; }
?>
would it be correct ?
