A repeat-order note is easier to use when it points to one approved reference photo. Save the photo beside the item name and the version that was accepted, rather than treating an older listing image as the full instruction.
Say what the image confirms
Write a short caption about the part of the result that the photo is meant to document, such as placement or reading order. A photo is useful evidence for a discussion, but it does not establish future availability, material performance, or a promised turnaround.
