My Preview shows old Input and new Input how can i show only new Input

When i Input 2 Images to Preview without Upload, it shows them just fine. The Problem comes when i pick other Files. They are added into the Preview instead of getting deleted. Basically now only the new 2 Images would be Uploaded but in the Preview he sees 4 Images. How can i delete the old Images when he Input new ones.

I figured a If Statement would help the Case but i am not sure how to write it.

This is my JS Preview:

$(function() {
    // Multiple images preview in browser
    var imagesPreview = function(input, placeToInsertImagePreview) {

        if ('.previewdeleter' ===('image') ){
            var deletepreview = ('previewdeleter')
        }

        if (input.files) {
            var filesAmount = input.files.length;

            for (i = 0; i < filesAmount; i++) {
                var reader = new FileReader();

                reader.onload = function(event) {
                    $('<div class="previewdeleter position-relative" data-item-id-div="input.files[i].length" style="height:200px;width: 200px; display: inline-block; position: relative !important;">' +
                        '<img alt="" src=' + event.target.result + ' style="height:200px;width: 100%; display: inline-block;">')
                        .appendTo(placeToInsertImagePreview);
                }
                reader.readAsDataURL(input.files[i],);
            }

        }


    };

    $('#images').on('change', function() {
        imagesPreview(this, '#previewHolder',);
    });

});

This is my HTML:

               <input value="" type="file" id="images" name="images[]" accept="image/*" multiple />
                <div id="previewHolder" data-item-id-div="input.files[i].length" multiple="" class="previewdeleter position-relative">
                </div>
