If picture area is ready to return as an array you then want retailer the picture subfield right into a variable and use the variable to output the array keys.
So in your case, it will be like this…
<?php whereas( have_rows('logo_list') ) : the_row();?>
<?php $picture = get_sub_field('picture'); ?>
<li><img src="<?=$picture['url']?>" alt="<?=$picture['alt']?>" /></li>
<?php endwhile;?>
Use the code beneath inside your loop to dump your $picture variable information so you may see all of the picture sizes and different picture information.
echo '<pre>' . print_r($picture, true) . '</pre>';
Very unusual what is going on right here.
Earlier than your loop strive including this to see all the information within the area.
<?php world $put up; ?>
<?php $area = get_field('logo_list', $post->ID); ?>
<?php echo '<pre>' . print_r($area, true) . '</pre>'; ?>
Put up the output once you’ve carried out this.
