The regular expressions work because of luck, they are not solid. See the 'wrong regex' comments. Also, the getstore(url, file) method needs <a href="http://host.org/dir/file" rel="nofollow">http://host.org/dir/file</a> as argument 1 and path/to/file.jpg as argument 2. Here is a working version: <pre><code>use WWW::Mechanize; use strict; use warnings; use LWP::Simple; my $ctime = time(); my $Home_page = 'www.condortk.com/'; my $output_file = "www.condortk.com-$ctime"; my $url = 'http://www.condortk.com/results.php?keyword=&Buscar.x=4&Buscar.y=7'; my $m = WWW::Mechanize->new(); $m->get( $url ) or die "unable to get $url"; my $Home_Con = $m->content; system( 'mkdir Images' ) if ( ! -d "Images" ); my $next = ''; my $page = ''; while ( $Home_Con =~ m/<div class="producto"><a href="([^"]*?)"/igs ) { # <-- wrong regex #print "Loop 1 $1 \n"; $m->get( "http://www.condortk.com/$1" ); # <-- wrong url my $list_content = $m->content; my $img_name = ''; my $img_folder = ''; my $image = ''; my $big_image = ''; while ( $list_content =~ m/<div\s*class="nombre2"><a\s*href="([^"]*?)"/igs ) { #print "Loop 2 $1 \n"; my $desc = ''; my $desc1 = ''; my $block = $Home_page . $1; $m->get( $1 ); my $content1 = $m->content; if ( $content1 =~ m/id="imgproducto"><img src="([^<]*?)"/is ) { $img_name = $1; # wrong url and 'save as' parameters if ( $img_name =~ m/\/\w+\/\w+\/(.*)$/is ) { my $basename = $1; my $get = "http://${Home_page}${img_name}"; my $save = "Images/$basename"; my $code = -1; if ( ! -f $save ) { $code = getstore($get, $save ); print "$get --> $save : $code\n"; } else { print "Skipping $save\n"; } #if ($code != 200) { print "$get --> Images/$save : $code\n"; } } } } } </code></pre> - <pre><code>$ perl dl.img.pl http://www.condortk.com/.../60504s_725x0.jpg --> Images/Images/60504s_725x0.jpg : 200 http://www.condortk.com/.../60508s_725x0.jpg --> Images/Images/60508s_725x0.jpg : 200 http://www.condortk.com/.../60501s_725x0.jpg --> Images/Images/60501s_725x0.jpg : 200 http://www.condortk.com/.../60020s_725x0.jpg --> Images/Images/60020s_725x0.jpg : 200 </code></pre>

2. COPreviously, when the script tried to get *www.moo.com/dir/img.jpg*, the server returned 400 (Bad Request) because the address was not prefixed with *http://*. You can use the return code to figure out what went wrong or to assert that the server understood the request.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
