There are two ways to link web page previews using our WordPress plugin.

1. You can use the built-in "link" function like so:

[thumb link="true"]https://shrinktheweb.com[/thumb]

or 

[stwthumb link="true"]https://shrinktheweb.com[/stwthumb]

Depending on your selection of tag to use.

2. You can manually wrap the tag with the HTML ahref link you want (good in case you want to link to something different from the screenshot; as in affiliate links):

<a href="https://shrinktheweb.com/aff/landing.html">[thumb]https://shrinktheweb.com[/thumb]</a>
