Sorry, I’m gonna be that guy. I understand the sentiment and this seems like a nice gesture, but the wording (maybe translation issue) is problematic. We should be clear that Mass is not directed to the people in the pews, but is a sacrifice offered to God. The primary purpose of those of us in the pews is to join our intentions, prayers, and sacrifices to this Sacrifice as one body, with the priest representing Christ as head (the pictures could instead be good reminders of who are joining in spirit, or for whom Mass is offered, if it is being offered for the intention of the parish). The traditional orientation of the priest makes this unity of purpose more clear and would likely make it easier for a priest to adjust to difficult circumstances like these. Even the way the priest faces for the readings have symbolic meaning in addition to simply directing the reading to the hearing of those in the pews (facing north for the Gospel, for example, is symbolic of the Church preaching the Gospel to the pagans).
