Problema com timthumb.php

Olá..derrepente, sem eu alterar configuração nenhuma as imagens na pagina principal do meu blog sumiram…não leem…

quando tento abri-las em outra janela aparece essa mensagem:

Warning: usort() expects parameter 1 to be array, boolean given in /home/theflami/public_html/blog/wp-content/themes/topzglow/timthumb.php on line 317

Aqui esta o blog: http://www.theflamingpie.com.br
