Google chrome a:visited background image not working

Question

(before I start I should say yes, I have done all the stupidity checks, yes the link is in my history and has been visited etc)

I\'m using Chrome version 6.0.472.63,

Answer 1

This is done for security reasons, as it was possible to load a lot of different images and detect which links the user had visited, any property sending an specific request, or loading a specific resource, depending on what the user has visited is technically seen as a security issue, as it can leak personal interests of the user.
