Portal:Mathematics/Selected picture
This page is part of the Mathematics Portal |
This is the collection of pictures that are being randomly selected for display on Portal:Mathematics. (This system replaces the previous "Featured picture" system that was in use until March 2014.)
To add a new image:
- Edit any existing subpage in the list below (link in upper-left corner of box) and copy its wikicode.
- Select the first non-existing subpage listed below (shown as a "redlink") to start editing that subpage, and paste the wikicode you just copied.
- If there is no "redlink" at the bottom of the list, edit this page and look for the code
{{numbered subpages|max=nn}}
. Increase nn by 2 (so there will still be a redlink after you create one new supage) and save the page.
- If there is no "redlink" at the bottom of the list, edit this page and look for the code
- Change all the relevant template parameters, as necessary.
- Note that the value of the
caption
parameter is used as the image's "alt text" and so should describe the appearance of the image as if explaining it to someone who cannot see it. You need not use a complete, grammatically correct sentence for this (e.g., "animation of blah" can be used instead of "This is an animation of blah."). - The
text
parameter is displayed as a paragraph of text below the image and should use complete, grammatically correct sentences to explain the meaning of the image and its significance from a mathematical perspective. - If the code you copied in step 1 used the
size
parameter to specify the image size, try removing that line to see whether the image looks acceptable at the default size. - Finally, note that we do not use the
gallery
,location
orarchive
parameters of the {{Selected picture}} template. Also, please do not change thepage = picture
orframecolor = transparent
lines.)
- Note that the value of the
- Save the new subpage and check that it's being displayed correctly in the list below. (You may have to purge the cache to see the changes.)
- If the default size is not acceptable (for example, if a raster image is being displayed larger than its actual size or if a GIF animation is showing up as a static image), the
size
parameter can be used to set the width (in pixels) of the image.
- If the default size is not acceptable (for example, if a raster image is being displayed larger than its actual size or if a GIF animation is showing up as a static image), the
- Edit Portal:Mathematics and locate the template call that randomly chooses the pictures for display:
{{Random portal component|max=nn|subpage=Selected picture|header=Selected picture}}
- Increase the number nn to reflect the new count of selected pictures, and save the page.
- And you're done.
