in first proglem :)
you set $Images = somefindprocess and when you set it to the view, you use
$images
problem: in declaration is first letter uppercase, in set for view you use
just lowercase :)
second problem: $articles array look likes {n}.Article.id
so you have to put for foreach $articles as $article and then you have
access to $article model via $article['Article']['yourkey']
