ebasa on "[Plugin: upPrev] Thumbnails not working after installing code"

Hi Marcin,

I changed the code to the code below, but it still isn't working.

<?php
add_action( 'iworks_upprev_image' , 'default_image' );
function default_image()
{
return '<img src="proper image uri" alt="" />';
}

Am I doing something wrong?
