+ This is a configuration option for images that
+ <application>Privoxy</application> is stopping. You have the choice <!-- of
+ the --> <!-- <application>Privoxy</application> logo, --> of a checkerboard
+ pattern, a transparent 1x1 GIF image (aka <quote>blank</quote>), or a custom
+ URL of your choice. Note that to fit this category, the URL must match both
+ the <quote>+image</quote> and <quote>+block</quote> actions.
+</para>
+
+<para>
+ If you want to see nothing, then change the <quote>+image-blocker</quote>
+ action to <quote>+image-blocker{blank}</quote>. This can be done from the
+ <quote>Edit Actions List</quote> selection at <ulink
+ url="http://p.p/">http://p.p/</ulink>. Or by hand editing the appropriate
+ actions file. This will only effect what is defined as <quote>images</quote>
+ though. Also, some URLs that generate the bright red <quote>Blocked</quote>
+ banner, can be moved to the <quote>+image-blocker</quote> section for the
+ same reason, but there are some limits and risks to this (see below).

+ This can be helpful for troubleshooting problems. It might also be good

+<para>
+ These are URLs that match something in one of
+ <application>Privoxy's</application> block actions (+block). It is meant
+ to be a warning so that you know something has been blocked and an easy way
+ for you to see why. These are handled differently than what has been defined
+ explicitly as <quote>images</quote> (e.g. ad banners). Depending on the
+ URL itself, it is sometimes hard for <application>Privoxy</application> to
+ really know whether there is indeed an ad image there or not. And there are
+ limitations as to what <application>Privoxy</application> can do to
+ <quote>fool</quote> the browser.
+</para>
+
+<para>
+ For instance, if the ad is in a frame, then it is embedded in the separate
+ HTML page used for the frame. In this case, you cannot just substitute an
+ aribitray image (like we would for a <quote>blank</quote> image), for an HTML
+ page. The browser is expecting an HTML page, and that is what it must have
+ for frames. So this situation can be a little trickier to deal with, and
+ <application>Privoxy</application> will use the <quote>Blocked</quote> page.
+</para>
+
+<para>
+ If you want these to be treated as if they were images, so that they can be
+ made invisible, you can try moving the offending URL from the
+ <quote>+block</quote> section to the <quote>+imageblock</quote> section of
+ your actions file. Just be forewarned, if any URL is made
+ <quote>invisible</quote>, you may not have any inkling that something has
+ been removed from that page, or why. If this approach does not work, then you are
+ probably dealing with a frame (or <quote>ilayer</quote>), and the only thing
+ that can go there is an HTML page of some sort.
+</para>
+<para>
+ To deal with this situation, you could modify the
+ <quote><filename>block</filename></quote> HTML template that is used by
+ <application>Privoxy</application> to display this, and make it something
+ more to your liking. Currently, there is no configuration option for this.
+ You will have to modify, or create your own page, and use this to replace
+ <filename>templates/blocked</filename>, which is what
+ <application>Privoxy</application> uses to display the <quote>Blocked</quote>
+ page.
+</para>
+<para>
+ Another way to deal with this is find why and where
+ <application>Privoxy</application> is blocking the frame, and
+ diable this. Then let the <quote>+image-blocker</quote> action
+ handle the ad that is embedded in the frame's HTML page.

+ There is not enough space to fit the entire page. Try right clicking on the

+ This will usually allow you to see the entire Privoxy <quote>Blocked</quote>
+ page, and from there you can see just what is being blocked, and why.
