No, I doubt it will since its not really "that type of game" but its also not close enough to being finished to think about a gallery or at least I think so.
It doesn't have that many CG art to begin with, what purpose would a gallery serve? I mean, it's right there at the top of this page: "Monster Girl Dreams is a text based BFRPG".
Due to how each zone is split up and repeatable in at least one way, I don't think a gallery is really necessary, especially not with the amount of save slots available
