I am going to try upside-down-ternet using
privoxy on my proxy server.
My question is, how do I implement this on
privoxy? My goal is to replace all ads with an image of my choice.
Have you read the quickstart guide? They specifically have a section for exactly what you want.
set-image-blocker - tells Privoxy what to display in place of an ad image that has hit a block rule. For this to come into play, the URL must match a block action somewhere in the configuration, and, it must also match an handle-as-image action.
The configuration options on what to display instead of the ad are:
pattern - a checkerboard pattern, so that an ad replacement is obvious. This is the default. blank - A very small empty GIF image is displayed. This is the so-called "invisible" > configuration option. http:// - A redirect to any image anywhere of the user's choosing (advanced usage).
Tell us where your encountering a problem. Try flesh out the question as much as possible. Help us help you. Are you having a issue with the configuration? Is it not showing the picture? Can you not install
