include('simple_html_dom.php');

foreach ($urls as $key => $url) {
    $url=trim($url);
$html=file_get_html($url);



$ep=$html->find('.post-container img');

So this call

$html=file_get_html($url);

is failing for (at least) some url, resulting in $html being false (which I learned from looking at the code, which is the *magic of open source*). Therefore, you need to handle the condition where $html is false.
