What would be the appropriate functions to:

1) Open an url and put the html in a variable.

2) Download a jpg from the above html and save it somewhere on disk.

Thanks!

Check out LWP and HTML:arser, then share any difficulties you run into to
get help.

Yep, I found out about LWP using perldoc.
I guess I can use get($picture_url) and save this to a file somewhere.

As you read a bit further through the documentation for LWP::Simple
(which is where I assume you read about get()), you'll come across the
getstore() function too

For beginners, the lwpcook doco ("The libwww-perl cookbook") explains a
lot of simple stuff very quickly. (type "perldoc lwpcook" at a prompt)

cheers,

1) Open an url and put the html in a variable.

use LWP::Simple;
my $html = get( $url );
if ( defined $html ) {
# HTML was downloaded OK
}

2) Download a jpg from the above html and save it somewhere on disk.

A bit more trickier, but still very easy with a lot of the modules out
there. The problem is that you might need to make absolute URLs out of
the links in the HTML you downloaded. The actual downloading is still
done with LWP::Simple's get() or getstore() functions.

Check out the HTML::LinkExtor documentation for a nice example on how to
extract links from HTML and make them absolute.

You'll be helped by the LWP::Simple module and HTML::LinkExtor
