This page highlights the finest images on Wikipedia. The featured picture criteria explains that featured pictures must be freely licensed or in the public domain, must be of a high technical quality, and must add significantly to at least one article on Wikipedia. There are currently 7,890 featured pictures, and they are categorized below by the topic they represent. All featured pictures are also available in a category.
One or more featured pictures are chosen as the picture of the day (POTD). You can include a box displaying the current POTD anywhere (e.g. your user page) by adding the text {{pic of the day}} or {{POTD}} where you want the picture to be shown.
