Here is the website http://ariadneswonderland.gr/ that all this conserns.
I dislike people that beg for help without having searched for a solution and i've done the best i could before coming here 
My code doesn't work, it might not even be close to correct but it was the best i could come up with.
On the homepage I'm using a Drop shadow box plugin
under the gallery to show a series of images of featured posts, as of right now, as i'm still building the website all you see is the White box under the gallery and a emoticon inside it.. What i'd like is to be able to do is have some code that pulls the 5 lastest posts from a category (in this case frontpage id 7) and Displays the Featured Post Image next to each other.
Code:
==============================
= X X X X X =
==============================
Where X is a Featured post image automatically retrieved instead of having to retrieve and add links every time i want to change a feature.
= is the automatically generated [dropshadowbox].
Any ideas/code/snipets/plugins that you might feel would work would be greatly appreciated.
So far however all i've come up with is this but i can't figure out how to implement the php into the post, phpexec and similar plugins don't seem to work for this, tho simple things like echo'test'; work fine. And making it a function doesn't work as it doesn't seem to return anything :S Obviously i need alot more coding experience but as of right now i'd like to just be done with this website 
PHP Code:
// fetching latest posts from specific category
$categoryId = 7;
$args = array('category' => categoryId , 'post_status' => 'publish', 'numberposts' => 5);
$posts = get_posts( $args );
foreach($posts as $post){
$feat_image_url = wp_get_attachment_url( get_post_thumbnail_id($post->ID) );
$post_url = get_permalink($post->ID);
}
