title: tv-get-export-image-link Variable
|
|
type: text/vnd.tiddlywiki
|
|
|
|
The <<.def tv-get-export-image-link>> [[variable|Variables]] controls the value of the `src` attribute on the HTML `img` element generated by the <<.wlink ImageWidget>> widget when the value of its `source` attribute is not the title of a tiddler.
|
|
|
|
The variable should be a [[function|Functions]] with the following parameter:
|
|
|
|
;src
|
|
: The value of the `source` attribute -- equivalent to the image name specified in <$link to="Images in WikiText">the shorthand syntax</$link> `[img[source]]`
|
|
|
|
The ability to override image URIs in this way can be useful when one is using the [[Node.js configuration|TiddlyWiki on Node.js]] to export a static version of a wiki.
