Image crop handoff: give both source and target dimensions

A clean crop handoff includes the original image, exported crop, target use, aspect ratio, output dimensions, and any protected subject margins. Explain whether the crop is meant for a thumbnail, banner, or full-size view; the same framing may not serve all three. Note if transparency or metadata should be retained. Ask the reviewer to inspect the actual exported file at its intended display size, not just the in-editor preview.
