With the help of ACF support and a friend, we came up with how to do this in functions.php
// Change ACF Gallery Button Text
function my_acf_input_admin_footer()
{
?>
<script type="text/javascript">
jQuery(document).ready(function(){
acf.add_action('load', function( $el ){
jQuery(".acf-block-body .acf-button.acf-gallery-add").each(function(index) {
this.innerText = "Add Images";
});
});
acf.add_action('append', function( $el ){
jQuery(".acf-block-body .acf-button.acf-gallery-add").each(function(index) {
this.innerText = "Add Images";
});
});
});
</script>
<?php
}
add_action('acf/input/admin_footer', 'my_acf_input_admin_footer');
