Create thumbnails of any web page using a choice of webthumb API services: WebToPicture, bluga.net, PagePeeper, ShrinkTheWeb.
Yes! The plugin is free. You can register for free and use with no charge the service to grab the thumbnails at one of the services, that are also free.
In the 0.x version there is a 'debug' feature activated that generates hidden HTML code.
In your browser rigth click and 'display source code' or similar to view HTML, then search for '<!-- start of WPF-WebThumb ...': here you can find useful info. There is one debug info for common includes and one for each image you try to display.
If you cannot fix, please send me copy of this code, or the URL of the page that is not working. You can use WP plugin support page. I'll be happy to help you!
There are pros and cons for the possible choices:
bluga.net requires a registration, you have 100 free shots per month. More if you pay.
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 (this feature not implemented jet)
shrinktheweb is very fast but requires registration and clicking on the image redirect you to a intermediate page in shrinktheweb.com. The image caching is available only to premium account and is not implemented by the plugin.
shrinktheweb caching image is now available for free users too! Just use 'shrinktheweb (img cache)' option.
Web2Picture is completely free, but has very slow response time (hours? days?) if thumb does not exists. So it is add as an option before grab the thumbs with any other service.
It is possible to use predefined templates (see dir 'templates') or define a custom template to display the thumbnails. Just create webthumbs-n.html in 'templates' dir and refer to is as template=n (n is an integer!)
The predefined templates you can choice between are:
0 : is just an <img /> tag with attributes src, alt, title, id
1 : is a simple box with title on the top (if specified) and url in the bottom (if specified) and the thumbnail in the middle
2 : is a small clickable box, useful to have many thumbnails on a row.
see examples at WPF-WebThumb developer's site
The plugin poll for an image ready, if it is not in about 1 minute it stops waiting and display a question mark image. Probably refreshing the page the image is then fetched.
When you request a thumbnail to PagePeeper chances are that it is ready in seconds; if not you can retrieve it later, but in this case an image with PagePeeper logo only is returned and cached.
You should delete the cached image to retrieve the correct one.
You can delete or update file by file using the 'Cache' tab in settings pages, or you can directly browse your site at the directory specified by 'thumbnails dir is:'.
Here you can find images with names that are 'close' ;-) to the domain names you thumbnailed: if you delete one or more of them a new cached image will be saved next time the thumbnail is requested.
