Wolfgang,
You're a keen observer! I have never imagined such a view of prayer at the "wailing wall".
This is one of the holiest places in Jerusalem. It is the surviving wall of the magnificent Jewish Temple, first built by Kind Solomon and then rebuilt after the return of Jews from captivity in Babylon.
Until recently, men prayed by the wall but now there is a section for women too. That was a major dogmatic fight as the ultra-orthodox have not yet grappled with the ideas of total equality of the sexes. The most orthodox men don't wish to be distracted from prayer by the intrusion of females. The women feel that they have equal rights in how they approach god in prayer.
Actually, the most extreme orthodox of many religions have so much more in common that one might first imagine by their labels. Thanks goodness, Jews do not think Judaism is the sole path to heaven or else they would be in India converting the poor and that society, for sure do not need any more sub-divisions!
The picture is so interesting as doug points out, as it frames just two individuals from a large assembly of worshipers. It shows that they are acting, each on his own, without mediation of a priest or intermediary in their voice to heaven
