Upload, browse, reorder, and auto-number your assets

Overwrite control, custom numbering, and deletion

A preview node that actually handles this pack's Python-list image format

Pick one image from a list by index — and unlike its sibling, it refuses out-of-range picks

Scale any image so its longest edge hits your target — then snap it to a friendly multiple
