Character Gallery

Hello. I would like to suggest adding an option for the character gallery that allows for conditions based on the story's progression, rather than relying solely on the number of messages exchanged with the user.

For example: a creator could add an image of the character fighting a goblin to the gallery, but this image would only become visible to the user once that event actually occurs within the story.

I think this would be a great addition and would help enhance the visual support for how stories unfold.

The difference between this and "branch story" is that "branch story" is developed as a parallel universe, instead this option would be in the same universe as visual support in the development of the story or in the creation of objectives within the story.
