Create thumbnails of any web page using a choice of webthumb API services: WebToPicture, bluga.net, PagePeeper, ShrinkTheWeb.
WebThumb create thumbnails of any web page.
You can choice a free service between:
bluga.net: you can register free of charge to have up to 100 thumbnails fetched per month; paying a fee this limit can be removed.
PagePeeper may be use with no registration, but the thumbnail generated is branded with their logo; if you register you can get 100,000 shots/month with no logo.
ShrinkTheWeb returns a not-cacheable image and requires registration, free service has limited IP access. (not reccomanded)
ShrinkTheWeb2 returns a cacheable image and requires registration, very fast.
WebToPicture is completely free, not requires registration nor is branded, but has very slow response time.
You can use a shortcode to place the thumbnail images anywhere in your posts or articles. A multi-widget is also available. It is possible to select the size of each thumbnail and some other options. Using a suitable template, may click on the thumbnail to go to the site and/or display a bigger thumbnail, etc.
Currently in beta, works with PHP 5.2.12 or higher: please report any issue you find, and any feature you want. I'll try to fix the firsts and to implement the seconds!
Very close to a first release (no know bugs, if found any please ask me for support!)
