How do I add photos to a trail?

On the edit page of a trail:

1. Click on "Add photo/video".
2. Click on the camera icon to select a photo from your computer. You can also simply drag and drop your photo.
3. The photo will be sent and then will disappear from this interface. When you have finished sending photos, click on "Close" and you will find your photos on the interface.
4. You can click on one of the circles to make one of the photos the main photo. It will then appear first, next to your trail name on the details page.
5. If you make a mistake, you can also delete a photo by clicking on the trash bin. The photo is permanently deleted and cannot be retrieved.
6. Click on "Save" to accept the changes.
