To save expanding this topic with another quote, this is in response to nooutlet responding to me.
Sorry, I understand you now. Yep, I would suggest the piclens view should just be for the gallery contents itself and not the sub galleries. If you choose to go to those galleries, piclens would then just show the contents of that gallery and so on.
Basically the viewer should have options, but the gallery owner should still have options to direct viewers accordingly.
Hopefully I'm making sense
