Form Image Upload Preview

Hi, have been using your Plugin for a couple months now and I am absolutely a big fan.
In some projects I have been using the acf_form() function.

Unfortunately images are not shown as a preview when selected.

I created a little snippet, which does so:

let file;
let regExp = /[0-9a-zA-Z\^\&\'\@\{\}\[\]\,\$\=\!\-\#\(\)\.\%\+\~\_ ]+$/;

$( '.acf-basic-uploader input[type="file"]' ).change(function(event) {
  file = '';
  file = this.files[0];

  if (file) {
    const reader = new FileReader();
    reader.onload = function () {
      const result = reader.result;

      var wrap = event.target.closest('.acf-image-uploader');
      elt = wrap.querySelector("div.image-wrap img");
      elt.src = result;

      var wrap_two = event.target.closest('.acf-field-image');
      wrap_two.classList.add("active");
    };
    reader.readAsDataURL(file);
  }

});

Just wanted to share it & maybe it will find its way in to the plugin :)
(it does support repeater fields as well)

Start by tracing the acf_form() image-upload path and the .acf-basic-uploader input shown in the issue. Check how the .acf-image-uploader and .acf-field-image elements are updated, then verify that selecting an image displays its preview for regular and repeater fields.
