This plugin dynamically shows preview screenshots of hyperlinks as tooltips on your WordPress site.
For the tooltip effect a jQuery plugin called “qTip2” is used internally.

The thumbnails are provided by http://thumbsniper.com and its API.
Imagens de tela
- Upload the directory ‘thumbsniper’ to the ‘/wp-content/plugins/’ directory
- Ative o plugin por meio do menu “Plugins” no WordPress
- Make your settings through the ‘ThumbSniper’ menu in WordPress
- Why does it take a couple of seconds until the preview image is shown?
It’s not a bug – it’s a mechanism.
The plugin doesn’t generate the thumbnails directly. The script sends a request for the thumbnail to the central ThumbSniper server. If the URL is requested for the first time, the thumbnail has to be created first. After this is finished, it’s cached on the ThumbSniper server and will be delivered much faster next time.
- How exactly does this work?
The shown tooltips contain a HTML “img” tag. The source URL of this tag points to the ThumbSniper service. The chosen image size and the URL of the current hyperlink are sent as parameters. The ThumbSniper service stores this data in a database. Then a thumbnail generator gets the order to generate a thumbnail for the stored URL. After successfully generating the image, the ThumbSniper service gets the image. The process of generating the image should take about 3 to 10 seconds. After this, the ThumbSniper service redirects to the correct thumbnail url and – here it is!
- Is the TumbSniper service free?
The ThumbSniper service is free of cost for you (not for me 🙁 ).
- Who’s the owner the ThumbSniper service?
It is written, operated and maintained by me, Thomas Schulte.

- I use ajax to get the thumbnail urls as jsonp results now. That’s cool because we get a nice gui-wait feedback while the thumbnails are loaded.
- added some more styles – the default from now on is “jtools”, you should give it a try!
- minor code changes
- Fixed a bug which might have caused some problems with Firefox/Mozilla.
- Changed the method to load the required jQuery library.
- The plugin uses plugins_url() instead of a hard-coded path now.
- Changed jQuery namespace to ThumbSniper to avoid conflicts.
- removed redundant code in the admin menu
- Changed the way jQuery() is called to avoid conflicts with other site scripts.
- Excluded urls were ignored. The missing code should do it’s work now.
- Added CSS attributes for the tooltip image to avoid disturbances with site-wide img-styles that might exist on a site.
- This is the first released version.
