#1515 redirect google image direct link

[Anonymous]

hi, i love your program
i would like to redirect the google image search link directly to the actual image

for example:
http://www.google.com.bo/imgres?imgurl=http://www.privoxy.org/user-manual/proxy_setup.jpg&imgrefurl=http://www.privoxy.org/user-manual/startup.html&usg=__Gjqx_ZoY9PxYOlx1aghV9gAjlIg=&h=453&w=575&sz=33&hl=es&start=5&zoom=1&tbnid=RgtXH7n0L_uGGM:&tbnh=106&tbnw=134&ei=45N_UMe7LoW6yAGQoYDYCg&itbs=1

directly to
http://www.privoxy.org/user-manual/proxy_setup.jpg

i've tried
{+redirect{https?://[\w-\.\/]+(\.jpg|\.jpeg|\.png|\.bmp)}}
.google./.*https?://[\w-\.\/]+(\.jpg|\.jpeg|\.png|\.bmp)

Try something like:

# Redirected URL = http://www.google.com.bo/imgres?imgurl=http://www.privoxy.org/user-manual/proxy_setup.jpg&imgrefurl=http://www.privoxy.org/user-manual/startup.html&usg=__Gjqx_ZoY9PxYOlx1aghV9gAjlIg=&h=453&w=575&sz=33&hl=es&start=5&zoom=1&tbnid=RgtXH7n0L_uGGM:&tbnh=106&tbnw=134&ei=45N_UMe7LoW6yAGQoYDYCg&itbs=1
# Redirect Destination = http://www.privoxy.org/user-manual/proxy_setup.jpg
{+redirect{s@.*url=(http://.*)&imgrefurl.*@$1@}}
.google./.*\?imgurl=http://

You're welcome.

The relevant documentation is:
http://www.privoxy.org/user-manual/actions-file.html#REDIRECT
which documents that the redirect{} action takes either an URL or a pcrs command as parameter.

Details on pcrs commands can be found in the filter file documentation as filters use pcrs commands as well.
http://www.privoxy.org/user-manual/filter-file.html#AEN5060
(I'll add a link to it.)

In short: the s marks the beginning of the pcrs command, the @ is the delimiter used to tell the regular expression from the substitution and the $1 specifies that the whole text matched with the regular expression should be substituted with the text matched by (http://.*).

When experimenting with redirects, it usually helps to enable redirect debugging:
