  Olá pessoal estou com um problemão, estou criando um site wordpress em cima de um tema que comprei pra um cliente, e quando posto imagens elas ficam com o caminho diferente, o site esta no endereço: http://www.murillobraz.com.br/temp sei que o problema esta no script porem não sei como resolver, se alguem puder me ajudar vou agradecer bastante, segue abaixo o script onde creio estar o problema.
