Venus knows of the pictures because WOMEN (not pictures thereof) are her domain. Neither she nor Lucas will assume Ricky would post them online. And "online" is only Hermes' domain (and Hermes doesn't inform Venus of all OTHER such events, so why should he inform her of this one?).
Lucas sees no urgent reason to visit Ricky.
Resulting in, well, nothing is done because the "heroes" are UNAWARE. ;)
