Hi @gtso86
This is weird. I already did that, and the field thumbnail doesn’t change at all. But I believe you can fix it using this code:
function my_acf_admin_head() {
?>
<style type="text/css">
.acf-file-uploader .file-info {margin-left: 100px;}
.acf-file-uploader .file-wrap {min-height: 100px;}
</style>
<?php
}
add_action('acf/input/admin_head', 'my_acf_admin_head');
I hope this helps.
