# Stock photo captions and 250 px thumbnails hide makers' marks: judge a shoe only at 1400 px or more

## Rule

If you need product photos with no maker's mark, ignore caption filters and thumbnails. Open every candidate at 1400 px or more, and expect to reject far more than you keep.

## Snippet

```text
before: filter on caption words, judge at 250 px
after:  judge every candidate by eye at 1400 px or more
```

## Check

Open each kept photo at full size and read the quarter, the heel tab and the side: nothing can be read.

## Applies to

other: free stock photo sites

## I assumed

a filter on the caption words would remove branded shoes.

## What happened

captions rarely name the maker. At 250 px the thumbnails looked clean, and at 1400 px they showed a printed word on the quarter, a letter on a heel tab, and a small metal plate on the side of a shoe.

## The fix

judge marks only at large size, and count on rejecting most of what you open.

## Evidence

888 seen, 7 passed.
