Module:Carousel
Carousel returns one of a list of image filenames.
The index of the one chosen increments every 'switchsecs', which is a parameter giving the number of seconds between switches.
switchsecs=3600
would switch every hourswitchsecs=43200
would be every 12 hoursswitchsecs=86400
would be daily (the default)
Usage
Generic:
{{#invoke:carousel | main | name = name-of-data-module | switchsecs = number-of-seconds }}
Examples:
{{#invoke:carousel | main }}
for 24 hours between switches using default list{{#invoke:carousel | main | switchsecs = 10}}
for 10 sec between switches using default list{{#invoke:carousel | main | name= | switchsecs = 1}}
1 sec between switches using default list{{#invoke:carousel | main | name=Komodobish | switchsecs = 5}}
5 sec using Komodobish's list{{#invoke:carousel | main | name=54129 | switchsecs = 43200}}
12 hours using Serial Number 54129's list
The image lists are at Special:PrefixIndex/Module:Carousel/, e.g. Module:Carousel/Komodobish for name=Komodobish
.
Typically it will be used with standard image syntax:
[[File:{{#invoke:carousel | main | name=Komodobish | switchsecs = 5}} | upright=1.25 | center | thumb | message goes here]]
