# Para disponibilizar as imagens na galeria você deverá usar o seguinte
# código através do comando chamar script.
#
# enable_picture(ID)
#
# EX   enable_picture(10)
#
# Para desativar a imagem use o código abaixo
#
# disable_picture(ID)
#
#==============================================================================
# Você deverá criar uma pasta com o nome "Gallery" onde as imagens deverão
# ser gravadas.
#
# Graphics/Gallery/
#
# A nomeação das imagens devem ser numéricas. (ID da imagem)
# 0.jpg    (Imagem não disponível.)
# 1.jpg
# 2.jpg
