Saving hotmail cpatcha images?

xpro · Feb 27, 2010

Hello

Hotmail's captchas work differently, with most sites I take the url of the captcha and save it. But with Hotmail if I access the captcha's url for the second time a different image loads. How can I save the same picture so I can send it to decaptcher?

Best Regards!

what language are you using?

my typical approach to that is to request the page, parse out the image link, then request the image and pull the image data from the return packet. then that is what you send in the decap post packet.

- edit -

that's the way most captcha systems work.

with perl I do the following to save image captchas using WWW::Mechanize

Code:

my $img_obj = $mech2->find_image( url_regex => qr{image\?c=} );

$image_data = $mech3->get( $img_obj->url,
               ':content_file' => 'captcha.jpg' );

this will save the image as captcha.jpg

with perl I do the following to save image captchas using WWW::Mechanize

Code:

$mech2 = $mech->clone();
my $img_obj = $mech->find_image( url_regex => qr{ts_image\.php} );

$image_data = $mech2->get( $img_obj->url,
               ':content_file' => 'captcha.jpg' );

this will save the image as captcha.jpg

PS: the cloning of the object is very important so that the session does not change
