You can see how bad my program is at:
http://www.perl.me.uk
It's called ebaypics
Advice from you in a new thread, would be very appreciated.
Don't put quotes around variables.
Found in /usr/lib/perl5/5.8.2/pod/perlfaq4.pod
What's wrong with always quoting "$vars"?

Don't use '&' with subroutine calls.

What's the difference between calling a function as &foo and foo()?
perldoc perlsub
# Generate weblinks
sub links {
my ($url, @list) = @_;
my @return;
foreach (@list) {
push @return, "$url/$_\n";
}
return @return;
}
# Put the generated weblinks from the subroutine links into an array
my @email_links = links($website, @thumbs);
This is what map() was invented for:
my @email_links = map "$website/$_\n", @thumbs;
