 | This is the template sandbox page for Template:POTD (diff). See also the companion subpage for test cases. |
Usage
editDisplays the English Wikipedia's current picture of the day (POTD) in a box of no more than 600 pixels wide, without the blurb (explanatory text), for use on user pages. To always display the current day's POTD, use {{POTD}}; to permanently feature a particular day's POTD, use {{POTD|date=[date]}}, where the [date] parameter can be given in any valid format.
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 POTDs 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}} |

{{POTD/[date]|size}} |
The size of the image, without the trailing px |

{{POTD/[date]|caption}} |

The Mandelbrot set is a two-dimensional mathematical set that is defined in the complex plane as the numbers for which the function does not diverge to infinity when iterated starting at . It was first defined and drawn by Robert W. Brooks and Peter Matelski in 1978, as part of a study of Kleinian groups, with Benoit Mandelbrot obtaining the first high-quality visualizations of the set two years later. Images of the Mandelbrot set exhibit an infinitely complicated boundary that reveals progressively ever-finer recursive detail at increasing magnifications; mathematically, the boundary of the Mandelbrot set is a fractal curve. The Mandelbrot set is well-known outside mathematics and is commonly cited as an example of mathematical beauty. These images, generated by a computer program, show an area of the Mandelbrot set known as "seahorse valley", which is centred on the point , at increasing levels of magnification. |
{{POTD/[date]|title}} |
A link to the article the image represents | Mandelbrot set |
{{POTD/[date]|texttitle}} |
A linkless short caption, also useful as an alt attribute | Mandelbrot set |
{{POTD/[date]|credit}} |
The credit line of the image, including the genre (e.g. photograph, painting) | Image credit: Wolfgang Beyer |
There are two additional predefined 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 also suitable for user pages.{{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 current 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/2025-08-30|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=2025-08-30}} or {{POTD|date=2025-08-30}}. Again, this system will only work for POTDs selected beginning January 1, 2007.
