create a php-gtk browser using GtkHTML

Hi,

I'm trying to come out with a sample code to illustrate the use of GtkHTML
by creating a simple php-gtk browser. The code is attached below.

The bullk of the code runs ok, except for the image loading part. Through
the signal 'url-requested', I managed to get the url of each image in the
signal handler.

In C, we would then do something like this:
        gtk_html_stream_write($stream, $img, strlen($img));

However, using the inspector, there's no GtkHTMLStream or similar method in
GtkHTML.
So, how do we load the image in GtkHTML? 

I've seen quite a number of postings in PHP-GTK-DEV between Alan and Andrei
titled "gtkhtml: yes - working!" But that was back in 2001, and I believe it
was for php-gtk1.

Was wondering if anyone has managed to get the image loading part to work
for GtkHTML, using the beta release of PHP-GTK2?

Regards,

Note: the sample code below requires the beta release of PHP-GTK2

<?php
$window = new GtkWindow();
$window->set_title($argv[0]);
$window->set_size_request(800, 640);
$window->connect_simple('destroy', array('Gtk','main_quit'));
$window->add($vbox = new GtkVBox());

$hbox = new GtkHBox();
$vbox->pack_start($hbox, 0);

$hbox->pack_start(new GtkLabel('URL: '), 0);
$hbox->pack_start($url_entry = new GtkEntry('http://www.google.com'));
$hbox->pack_start($go_button = new GtkButton('Go'), 0);
$go_button->set_size_request(32, -1);

$scrolled_win = new GtkScrolledWindow();
$scrolled_win->set_policy( Gtk::POLICY_AUTOMATIC,Gtk::POLICY_AUTOMATIC);
$vbox->pack_start($scrolled_win);
$gtkhtml = new GtkHTML(); // note 1
$scrolled_win->add($gtkhtml);

$gtkhtml->connect('url-requested', 'on_url_requested'); // note 2

$url_entry->connect('activate', 'on_url_entry_activate', $go_button); //
note 3
$go_button->connect('clicked', 'on_go_button', $url_entry, $gtkhtml); //
note 4
$go_button->clicked();

$window->show_all();
Gtk::main();

function on_url_entry_activate($entry, $go_button) {
    $go_button->clicked(); // note 5
}

function on_go_button($button, $url_entry, $gtkhtml) {
    $url = $url_entry->get_text(); // note 6
    $html_text = file_get_contents($url); // note 7
    $gtkhtml->set_base($url);
    $gtkhtml->load_from_string($html_text); // note 8
}

function on_url_requested($gtkhtml, $url, $stream) {
    echo "image url = $url\n"; // note 9

    // load the image
    $handle = fopen($url, "rb");
    $img = '';
    while (!feof($handle)) {
        $img .= fread($handle, 8192);
    }
    fclose($handle);

    // in C, we would then do this
    // gtk_html_stream_write($stream, $img, strlen($img));
    // gtk_html_stream_close($stream, (strlen($img)<0) ?
    // Gtk::HTML_STREAM_ERROR:Gtk::HTML_STREAM_OK);
    // However, there's no GtkHTMLStream or similar method in GtkHTML.
    // So, how do we load the image in GtkHTML?
}
