On some of our Public Pages, like CMB and EduCMB we placed several Link Modules to show links to content on the website of our library. The Link Module then displays a Thumbnail from that page/site.
Quick contact with Netvibes, resulted in quick action: they decided to block thumbnails for www.rug.nl at once, and investigate. My question to them : is the rug-site hijacked or the Thumbshots.org-site?
The outcome is still unsure, they now noticed trouble with Thumbshots and Google Groups as well.
They DID act quickly again in adjusting the Link Module: you now can turn the Thumbnail ON or OFF!.
