Hello,
Have a look at the different "ad.doubleclick.net" addresses included in the web site.
Find out the ip address and put them in your /etc/hosts file like this:
206.65.183.95 ad.doubleclick.net
206.65.183.95 uk.doubleclick.net
206.65.183.95 ad.uk.doubleclick.net
195.154.195.154 ad.fr.doubleclick.net
This will solve the loading time of the different websites with konqueror, firefox etc( sticking to load 90% of the images of the web site).
This issue doesn't seem to exist when you use Opera.
Kind regards
Jens
