Retry unchanged image sets after preload failures

When every window.Image() preload fails once (for example because the remote host briefly times out), setState still records state.key = normalizedKey. This early return then skips all future preload attempts for the same images prop, so a rerender of the same search result stays stuck in the empty state and shows No images found until the component is remounted or the query changes. That makes transient image/CDN failures permanent for the lifetime of the message.
