Module:InfoboxImage
This Lua module is used in system messages, and on approximately 4,280,000 pages, or roughly 257366% of all pages. Changes to it can cause immediate changes to the Wikipedia user interface. To avoid major disruption and server load, any changes should be tested in the module's /sandbox or /testcases subpages, or in your own module sandbox. The tested changes can be added to this page in a single edit. Please discuss changes on the talk page before implementing them. |
This module is subject to page protection. It is a highly visible module in use by a very large number of pages, or is substituted very frequently. Because vandalism or mistakes would affect many pages, and even trivial editing might cause substantial load on the servers, it is protected from editing. |
Overview
This module is used within infoboxes to process the image parameters and tidy up the formatting of the result.
Parameters
Parameter | Description |
---|---|
image | Required. The main parameter that should be passed over which contains the image info. |
size | Size to display image. |
maxsize | Maximum size to display image. Note: If no size or sizedefault params specified then image will be shown at maxsize. |
sizedefault | The size to use for the image if no size param is specified. Defaults to frameless. |
alt | Alt text for the image. |
title | Title text for image (mouseover text). |
border | If yes, then a border is added. |
page | The page number to be displayed when using a multi-page image. |
upright | If upright=yes, adds "upright" which displays image at 75% of default image size (which is 220px if not changed at Special:Preferences). If a value, adds "upright=value" to image, where values less than 1 scale the image down (0.9 = 90%) and values greater than 1 scale the image up (1.15 = 115%). |
center | If yes, then the image is centered. |
thumbtime | thumbtime param, used for video clips. |
suppressplaceholder | If no, then will not suppress certain placeholder images. See § Placeholder images which can be suppressed. |
link | Page to go to when clicking on the image. |
class | HTML classes to add to the image. |
Note: If you specify the maxsize or sizedefault params, then you should include the px after the number.
Parameters displayed in image syntax
All parameters:
{{#invoke:InfoboxImage | InfoboxImage | image={{{image}}} | size={{{size}}} | maxsize={{{maxsize}}} | sizedefault={{{sizedefault}}} | upright={{{upright}}} | alt={{{alt}}} | title={{{title}}} | thumbtime={{{thumbtime}}} | link={{{link}}} | border=yes | center=yes | page={{{page}}} | class={{{class}}} }}
[[File:{{{image}}}|page={{{page}}}|{{{size}}}|center|alt={{{alt}}}|link={{{link}}}|border|upright={{{upright}}}|thumbtime={{{thumbtime}}}|class={{{class}}}|{{{title}}}]]
When "size" and "maxsize" are defined, the smaller of the two is used (if "px" is omitted it will be added by the module):
{{#invoke:InfoboxImage | InfoboxImage | image={{{image}}} | size=300px | maxsize=250px }}
[[File:{{{image}}}|250px]]
When "size" is not defined, "sizedefault" is used, even if larger than "maxsize" (in actual use "px" is required after the number; omitted here to show it is not added by the module):
{{#invoke:InfoboxImage | InfoboxImage | image={{{image}}} | sizedefault=250px | maxsize=200px }}
[[File:{{{image}}}|250px]]
When "size" and "sizedefault" are not defined, "maxsize" is used (in actual use "px" is required after the number; omitted here to show it is not added by the module):
{{#invoke:InfoboxImage | InfoboxImage | image={{{image}}} | maxsize=250px }}
[[File:{{{image}}}|250px]]
When "size", "sizedefault", and "maxsize" are not defined, "frameless" is added, which displays the image at the default thumbnail size (220px, but logged in users can change this at Special:Preferences) and is required if using "upright" to scale the default size:
{{#invoke:InfoboxImage | InfoboxImage | image={{{image}}} }}
[[File:{{{image}}}|frameless]]
Use of "upright" without a number value, which displays the image at approximately 75% of the user's default size (multiplied by 0.75 then rounded to nearest 10):
{{#invoke:InfoboxImage | InfoboxImage | image={{{image}}} | upright = yes }}
[[File:{{{image}}}|frameless|upright]]
When "alt" is used without "title", the alt text is also used as the title:
{{#invoke:InfoboxImage | InfoboxImage | image={{{image}}} | alt = Alt text }}
[[File:{{{image}}}|frameless|alt=Alt text]]
For more information, see Wikipedia:Extended image syntax.
Sample usage
|image = {{#invoke:InfoboxImage|InfoboxImage|image={{{image|}}}|upright={{{image_upright|1}}}|alt={{{alt|}}}}}
