Show button when checkbox checked.

Show button when checkbox checked.

Hello guys, i have a small script to show the button when the checkbox checked. But the problem now is.. that I have multiple checkboxes and   when I checked them all and uncheck one.. the button hides again
here is my code: 

$(document).ready(function() { var $sub = $("#removImg").hide(); $(document).on('change', 'input[name="chkboxplat[]"]', function() { $sub.toggle(this.checked); }); });
I really appreciate your help :)
Kind regard,
Henk
