This plugin accesses the ShrinkTheWeb API to automatically replace special tags in posts with website screenshots, where desired.
This plugin allows any WordPress user to easily add thumbnail previews of websites right in the content of their posts using a simple
[stwthumb]http://www.yourwebsite.com[/stwthumb] format. Loads of examples are available within the plugin documentation (you'll see it when you activate the plugin).
The plugin requires a free or paid account from the thumbnail provider service ShrinkTheWeb.com. No purchase is required to use the plugin or the free service.
