Not sure if this will cause your issue, but the first think to change is that you need to get the repeater before you use have_rows().
$images = get_field('images');
if (!empty($images)) {
$count = count($images);
}
if (have_row('images')) {
// your code continues
The next issue is that you are attempting to use a text field like an image field. A text field only returns the value entered into it
$image = get_sub_field('image');
..... background: url('<?php echo $image; ?>') ...
