This plugin adds an [xkcd] shortcode tag to WordPress. You can use it to embed the XKCD webcomic into your posts and pages.
It takes a num attribute that specifies the number of the XKCD comic to embed. For Eg:- To embed the 100th comic use,
[xkcd num='100']
When the num attribute is omitted the latest XKCD comic is shown instead.
