A list of pictures runs these nodes once per picture, and the panels only showed one of them (#204). Arrows (2 / 5) now appear on the node when a run brings more than one picture: Compare steps through its pairs, A and B together, and Erase saves the pair on screen. The shared preview panel gets the same arrows, so Save Image, Mask Refine, Mask by Name, LaMa Inpaint and Select Frame step through their results. A node too narrow for the arrows widens to fit while they show.
