Não consigo descobrir como centralizar as imagens. O objetivo é centralizar as imagens e torná-las grandes o suficiente para ultrapassarem a linha de corte.
Opcionalmente: É possível controlar o quão próximas as imagens estão (em outras palavras, quão grande é o espaço entre a borda inferior de uma imagem e a borda superior de outra imagem).

A formulação do problema não é muito clara, mas talvez seja isso que você deseja.
