The picture of the day is an image which is automatically updated each day with an image from Wikipedia:Featured pictures. Although the picture of the day is generally scheduled by one editor (currently Crisco 1492), anybody can contribute. If you have concerns about the current picture of the day, please post at Wikipedia:Main Page/Errors. If you have concerns about an upcoming POTD, consider either fixing it yourself or posting at Wikipedia talk:Picture of the day or User talk:Crisco 1492.

Picture of the day

The Biham–Middleton–Levine traffic model for a 144 x 89 lattice, with a traffic density of 39%. The model has self-organized to a disordered intermediate phase. The red cars and blue cars take turns to move; the red ones only move rightwards, and the blue ones move downwards. Every time, all the cars of the same colour try to move one step if there is no car in front of it. This video has been sped up such that only one in four frames is shown.

Guidelines[edit]

  1. The picture must already be a featured picture. To nominate a picture for that honor see featured picture candidates.
  2. Featured images are currently selected in roughly the order in which they were promoted (i.e. a First In, First Out order). See the featured pictures candidates archive for this order. Exceptions are made for anniversaries of events, or for national holidays.
  3. Not all featured pictures will appear as POTD. Wikipedia:Picture of the day/Unused has a list of those that have been skipped.

POTD on your user page[edit]

You can insert the image on your user page or talk page by adding the text {{Pic of the day}} (this version is shown above). It will be displayed in a box of no more than 600 pixels wide, and will include a small amount of text based on the article in which the image appears. A no-text version is also available via {{POTD}}.

It is also possible to create your own custom POTD layouts, in case the already-existing versions will not look good within your user page design. Mix and match the following components to make your own. This system will only work for Pictures of the day selected 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 Image: prefix. Biham-Middleton-Levine traffic model self-organized to a periodic intermediate phase.ogv
{{POTD/[date]|size}} The size of the image, without the trailing px. 320
{{POTD/[date]|caption}} The image caption. The Biham–Middleton–Levine traffic model for a 144 x 89 lattice, with a traffic density of 39%. The model has self-organized to a disordered intermediate phase. The red cars and blue cars take turns to move; the red ones only move rightwards, and the blue ones move downwards. Every time, all the cars of the same colour try to move one step if there is no car in front of it. This video has been sped up such that only one in four frames is shown.

See the periodic intermediate phase

{{POTD/[date]|title}} A link to the article the image represents. Biham–Middleton–Levine traffic model
{{POTD/[date]|texttitle}} A linkless short caption, also useful as an alt attribute. Biham–Middleton–Levine traffic model

There are two additional pre-defined layouts

  • {{POTD/{{#time:Y-m-d}}|column}}: This has the image and caption above each other with no borders. Used on some of the Main Page alternatives and suitable for user pages as well.
  • {{POTD/{{#time:Y-m-d}}|row}}: This has the image and caption encapsulated in (usually) a single table row. This is the version used on the Main Page.

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 POTD is {{POTD/2016-09-28|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=2016-09-28}} or {{POTD|date=2016-09-28}}. Again, this system will only work for Pictures of the day selected beginning January 1, 2007.

Usage

POTD thumb[edit]

When you want to display the POTD 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[edit]

If you want to permanently include a Picture of the day 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}}.

PsOTD selected from May 2004 through October 2004 are only accessible in month-at-a-time archives and can only be placed on user pages by using standard image syntax.
