Submit a photograph

The photographs in this guide are under a Creative Commons licence or in the public domain and show free-living wild mammals. Anyone with such a photograph can offer it here.

Each species has one main photograph and, below it, additions: a young animal, the summer or the winter coat, the animal in a posture that gives the species away. And signs: a print in mud or snow, droppings, feeding signs, a form or a burrow. That is where the guide is thinnest — every species page has a signs panel, and for many species it is still empty. A sharp photograph of a sign is therefore as welcome here as a photograph of the animal itself. A submission is considered if it shows something the page still lacks, or is clearly better than what is there. The author judges every submission himself; nothing goes on the site automatically. Replies are sent by e-mail.

What a photograph must meet

Where the guide still lacks a photograph

For these species no photograph of a living wild animal with a suitable Creative Commons licence exists:

The form

JPEG or PNG, landscape, long side at least 1600 pixels, at most 20 MB. An iPhone converts a HEIC photo by itself.

Type to search by English, Dutch, Spanish or scientific name. For a sign: the species that left it.

Only needed if the photograph itself carries no date.

As it should appear under the photograph: region, site or town. For a burrow, an earth or a winter roost the region is enough.

This is how the name will appear under the photograph and on the sources page.

Only for replies. The address never appears on the site and is kept as long as the photograph is in the guide.

The guide carries CC0, public domain, CC BY, CC BY-SA, CC BY-NC and CC BY-NC-SA. CC BY 4.0 is the lightest: free use with attribution. An NC licence rules out commercial use; the guide itself is non-commercial. ND licences (no adaptations) are not accepted.

Optional: what the photograph shows, or why this one. For a sign it helps to say what gives the scale, and what the print is set in — mud, sand, snow.

What happens with the data: the photograph is reduced to 2048 pixels and stored without the location data a camera adds. Name, place and date go with the photograph; the e-mail address does not. A photograph that is not taken up is deleted.
