    Hi everybody , I'm about to try to display an RSS feed on my web page.
    I can display links to descriptions and titles of RSS but I can not do display images of the links.
    Here is an example of what I want to do : http://dupont-orthez.notaires.fr/
    i use rsslib :
    <?php
/*
RSS Extractor and Displayer
(c) 2007-2009 Scriptol.com - Licence Mozilla 1.1.
rsslib.php

Requirements:
- PHP 5.
- A RSS feed.

Using the library:
Insert this code into the page that displays the RSS feed:

<?php
require_once("rsslib.php");
echo RSS_Display("http://www.xul.fr/rss.xml", 15);
?>

*/
$RSS_Content = array();

function RSS_Tags($item, $type)
{
$y = array();
$tnl = $item->getElementsByTagName("title");
$tnl = $tnl->item(0);
$title = $tnl->firstChild->textContent;

$tnl = $item->getElementsByTagName("link");
$tnl = $tnl->item(0);
$link = $tnl->firstChild->textContent;

$tnl = $item->getElementsByTagName("description");
$tnl = $tnl->item(0);
$description = $tnl->firstChild->textContent;

$tnl = $item->getElementsByTagName("image");
$tnl = $tnl->item(0);
$image = $tnl->firstChild->data;

$tnl = $item->getElementsByTagName("pubDate");
$tnl = $tnl->item(0);
$date = $tnl->firstChild->textContent;
$date = date("d/m/Y", strtotime("$date"));

$y["title"] = $title;
$y["link"] = $link;
$y["description"] = $description;
$y["image"] = $image;
$y["date"] = $date;
$y["type"] = $type;


return $y;
}


function RSS_Channel($channel)
{
global $RSS_Content;

$items = $channel->getElementsByTagName("item");

// Processing channel

$y = RSS_Tags($channel, 0); // get description of channel, type 0
array_push($RSS_Content, $y);

// Processing articles

foreach($items as $item)
{
$y = RSS_Tags($item, 1); // get description of article, type 1
array_push($RSS_Content, $y);
}
}

function RSS_Retrieve($url)

$title = $article["title"];
$link = $article["link"];
$page .= "<li><a target=\"_blank\" href=\"$link\">$title</a></li>\n";
