There are situations in which no trackers are safe
For activist computer users like myself, no tracking servers or 3ed party ad servers can be allowed access. Since a 2008 police raid that stole an encrypted computer from me but got no useful information for the other side, I have taken computer security very seriously. It's no longer enough to block 3ed party cookies, hasn't been for years. Third party content, ad or otherwise, must always be considered dangerous in a world of pervasive record-keeping. "Cookieless tracking" and browser/device fingerprinting are on the rise. Iovation, Bluecava, Scout Analytics, several other firms, and possibly Google are building device "credit history" databases. Supercookies and Flash cookies have been around for years. All of this can be blocked.

The image is an HTML link to the advertiser's own site. Might be possible to make the image and link always have the same name and destination, with the locally-cached image thus always having the same name, and updating the secondary HTML link like would be done in /etc/alternatives in Ubuntu, that would remove any need to dicker with the front page itself. If I wanted to run rotating public service announcements with big images and bold text at the top of an activist website, this is exactly how I would do it.
