WordPress.org

This plugin allows any WordPress user to easily add thumbnail previews of websites right in the content of their posts using a simple [thumb]http://www.yourwebsite.com[/thumb] 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.

Other Cool Features

• Option to enable mouseover previews (you see a screenshot of a link if a website visitor hovers the mouse over any external links on the site).
• Option for capturing inside pages (rather than just the homepage of a website).
• Plenty of examples in the plugin documentation
• Plugin automatically shows you which features are available based on your account type.

Supported STW PRO features

• Caching of thumbnails (Basic or PLUS accounts only)
• Custom thumbnail image quality (PRO upgrade feature)
• Full length image captures (PRO upgrade feature)
• Custom thumbnail sizes in addition to the standard STW thumbnails.
