JavaScript: Does not load the thumbnail image after sending to the server / upload?

Click to load the image, it sends to the UPLOADS folder the image file, however it does not return after sent the minute, but when you click F5 the image loads, what can it be?

Add.php

<input type="file" class="hidden" id="uploaderButton" name="file" data-url="<?php echo $langPrefix; ?>/ajax/upload/?apid=<?php echo $apid; ?>" multiple>
