Pictures are not displayed for me. I've reached one of them using the source code of the web page and landed on a 403 error :
"Your client does not have permission to get URL /Eu68gnuzOr2-jwIAfu27kqxn2svr2KApmI-37Pgy2KzCAoZbDq0H3ca-QtJJea8cdYLO from this server. "
Do you host your pictures on Google+? It may be the problem.
Try with an other hosting website, like imgur
