Not showing image when edit a resource item

[wemersonrv]

Hi, i crop and upload the image fine and it's shown right in index and details page. But when edit a row, the image is not shown. See my code:

ImageCropper::make('Avatar', 'avatar')
    ->disk('my_custom_disk')
    ->path('images/usuarios/'.str_pad($this->id, 10, "0", STR_PAD_LEFT))
    ->preview(function () {
        if (!$this->value) return null;

        $url = Storage::disk($this->disk)->url($this->value);
        $filetype = pathinfo($url)['extension'];
        return 'data:image/' . $filetype . ';base64,' . base64_encode(file_get_contents($url));
    })->avatar(),

I think it's a good idea to preview the image when editing too... but only update it when user re-crops the image, upload & crop a new image.
