The picture of the day (POTD) is a section on the Main Page of the English Wikipedia that is automatically updated every day with one or more of its featured pictures, accompanied by a blurb. Although it is generally scheduled and ed by a small group of regular ors, anyone can contribute. If you have concerns about today's or tomorrow's POTDs, please post at Wikipedia:Main Page/Errors. If you have concerns about upcoming POTDs, consider either fixing it yourself or posting at Wikipedia talk:Picture of the day.

Today's featured picture

Thysanozoon nigropapillosum

Thysanozoon nigropapillosum, the yellow-spotted flatworm, is a species of marine flatworm in the family Pseudocerotidae. The species is native to the tropical Indo-Pacific region, where it lives in shallow reef habitats. Flatworms are hermaphrodites, each being able to act as either male or female. As a donor of sperm, it can grip the margin of the recipient's body, using its two penises in a chopstick-like manner, and deposit sperm on the surface of the skin of the recipient, even while it is actively swimming.

This picture shows a T. nigropapillosum photographed in Manta Ray Bay, on the island of Yap in the Federated States of Micronesia. The flatworm is seen swimming to the right at a depth of 12 metres (40 ft) by undulating the margins of its body. The pseudotentacles at the front have simple eyes and sensory receptors to enable the flatworm to find tunicates on which it feeds.

Guidelines[]

Pictures of the day on your user page[]

You can insert the picture of the day on your user page or talk page by adding the text {{Pic of the day}}. It will be displayed in a box of no more than 600 pixels wide and will include the blurb associated with the picture. A version without text is also available via {{POTD}}.

It is also possible to create your own custom POTD layouts, in case you do not wish to use the existing versions. Mix and match the following components to make your own. This system will only work for pictures of the day beginning January 1, 2007. Be sure to replace [date] with an appropriate date value. For a dynamically updating version, use {{#time:Y-m-d}} (example: {{POTD/{{#time:Y-m-d}}|image}}).

Template Description Renders as
{{POTD/[date]|image}} The name of the image, without the File: prefix Yellow papillae flatworm (Thysanozoon nigropapillosum) (cropped).jpg
{{POTD/[date]|size}} The size of the image, without the trailing px 400

There are two additional predefined layouts:

It is also possible to permanently feature a POTD for a selected day. Just add a specific value for the date you want. For example, today's picture of the day is {{POTD/2020-04-09|image}}. Likewise, you can use date parameters with the other templates as well. If you like the pre-made formats, you can use date parameters there as well, like this: {{Pic of the day|date=2020-04-09}} or {{POTD|date=2020-04-09}}. Again, this system will only work for pictures of the day beginning January 1, 2007.

Usage

Random picture of the day[]

Use {{User:My Chemistry romantic/Templates/Random POTD}} to display a randomly selected picture of the day.

{{User:Tyw7/picofday}} also displays a randomly selected POTD, but without the header and footer.

As a thumbnail[]

When you want to display the picture of the day like an ordinary thumbnail, similar to {{WP:Wikimedia Commons/POTD}}, you can use {{POTD Wikipedia}}. For instance, if you want a thumbnailed version, floated right, you can use {{POTD Wikipedia|float=right|title=yes|thumb=yes}}.

Older pictures of the day[]

If you want to permanently include a POTD that was selected between November 1, 2004 and December 31, 2006, use the following: {{Wikipedia:Picture of the day/[month] [day], [year]}} or {{Wikipedia:POTD/[month] [day], [year]}}. For example, {{Wikipedia:Picture of the day/December 31, 2006}}.

Pictures of the day selected from May 2004 through October 2004 are only accessible in month-at-a-time archives (see below) and can only be placed on user pages by using standard image syntax.
