@fcavanha10,

how to display only "two posts"?

Go to http://your-blog-site-url-here/wp-admin/options-reading.php and select 2 items for news.

how to display the image Article and description with fewer characters put the article link in the description

Add Featured Image to RSS
Go to your theme folder and add next code to your functions.php file:

/**
 * Add Featured Image as a separate RSS item.
 *
 */
add_action('rss2_item', 'add_featured_image_node');

function add_featured_image_node() {
    global $post;
    if(has_post_thumbnail($post->ID)):
        $thumbnail = get_the_post_thumbnail( $post->ID );
        echo("  <featuredImage>{$thumbnail}</featuredImage>\n");
    endif;
}

Display Featured Image and other information you want
Copy the code from the first post at this page (see above gistfile1.php) and replace foreach cycle with next code:

foreach ($xml->channel->item as $item) {
    echo '<h2><a href="' . $item->link . '">' . $item->title . '</a></h2>';
    echo '<img src="' . $item->featuredImage->img['src'] . '" width="100" height="100" alt="' . $item->featuredImage->img['src'] . '" class="' . $item->featuredImage->img['class'] . '">';
    echo '<p>' . $item->description . '<a href="' . $item->link . '">Read more: ' . $item->title . '</a></p>';
}

You can modify an output HTML code for your purposes and style it with CSS.

CURLOPT_ENCODING does not actually mean what you think it means:
