Hi Martin,

that's the address that the image is linkted to (where clicking the
image leads), but the address of the image itself. You can determine
that address by right-clicking the image and opening it (some browsers
even have a "copy image location" option.

You can then add the URL to a  { +block +handle-as-image }  section
in your actions file as you did, and the image is gone.

Sadly, for some images on n-tv.de, it is hard to tell from the URL if
they are ads nor not, so we'd either need an exhaustive list, or
filter the image tags from the pages based on context (Note the
word "Anzeige" above them).

No need to restart Privoxy. Config changes have immediate effect.

That's because you blocked the URL as an image, i.e. instead of the
remote page, your browser gets a 4x4 image (See the mini-checkerboard
in the top left corner?)

To find out, open the image, and enter its URL into the form at
http://config.privoxy.org/show-url-info. You'll see that the URL
(http://www.n-tv.de/shared/werbung/parship_130x80.jpg) matches a
generic mark-as-image and a generic ad blocker section in default.action:

{+handle-as-image }
/.*\.(gif|jpe?g|png|bmp|ico)($|\?)
{+block }
/(.*/)?(publicite|werbung|rekla(ma|me|am)|annonse|maino(kset|nta|s)?/)

What's even more convenient is to open the image and then use the
"Privoxy - Why?" Bookmarklet from
http://www.privoxy.org/user-manual/appendix.html#BOOKMARKLETS
which will take you directly to the page that shows all matches
and the resulting actions for the URL.
