During a story, it is common for an entity to change physically or visually while keeping the same name. Examples: * A spaceship is modified or upgraded * A character is transformed into another species * A virus turns a character into a zombie * An artifact that looked like a staff is revealed to be a shotgun * The protagonist’s village becomes a military installation Because of this, a single reference image for a Codex entry is often not enough. Suggestion: allow multiple images to be attached to a single Codex entity. Additionally, it could be useful if images could change automatically through Codex Progressions , so that once a certain point in the story is reached, the reference image updates to reflect the new state of the entity.
