## Rule

If a side view is rejected for a printed mark, open the neighbouring IDs of the same upload. They are often the other side of the shoe, and the inner side often carries no mark.

## Snippet

```text
before: shoe-1215384, outer side, a printed device: rejected, move on
after:  shoe-1215385, the next ID, the inner side of the same trainer: no device
```

## Check

Open the neighbour at full size and read its side: nothing can be read.

## Applies to

other: free stock photo sites

## I assumed

a photograph rejected for a mark ruled out that shoe.

## What happened

one photographer shot the same trainer from both sides. The outer sides have a printed device, and the inner sides have none. Those inner sides are among the very few pure-profile photographs with no mark that the search found.

## The fix

look at the rest of an upload before leaving it.

## Evidence

two of the seven, `coral-runner` and `blue-runner` in `PHOTOS.md`.
