|''Name''|TiddlySpaceTiddlerIconsPlugin|
|''Version''|0.8.10|
|''Status''|@@beta@@|
|''Author''|Jon Robson|
|''Description''|Provides ability to render SiteIcons and icons that correspond to the home location of given tiddlers|
|''Source''|http://github.com/TiddlySpace/tiddlyspace/raw/master/src/plugins/TiddlySpaceTiddlerIconsPlugin.js|
|''Requires''|TiddlySpaceConfig BinaryTiddlersPlugin ImageMacroPlugin TiddlySpacePublishingCommands|
!Notes
{{{<<tiddlerOrigin>>}}} shows the origin of the tiddler it is being run on.
In TiddlySpace terms this means it will determine whether the tiddler is external, public or private.
Where private it will analyse whether a public version exists and distinguish between the different scenarios.
If a tiddler is external, the SiteIcon of that external space will be shown

!Parameters
width / height : define a width or height of the outputted icon
label: if label parameter is set to yes, a label will accompany the icon.
