Displaying web site screenshot thumbnails with MediaWiki

For displaying web site screenshot thumbnails with MediaWiki, you have to write the full external link image (ending with ".jpeg") provided by www.robothumb.com.

You have to set true in your LocalSettings $wgAllowExternalImages

The syntax is simple :

http://www.robothumb.com/src/ [url]@[size](.jpg)

where [url] is the url of the page to be displayed, example : http://www.mywebsite.com

available sizes for the parameter [size] are :
 * 100x75
 * 120x90
 * 160x120
 * 180x135
 * 240x180
 * 320x240
 * 560x420
 * 640x480
 * 800x600

The full external link image could be stored into a semantic value and displayed easily.
