Scalars in your @items array are hash references. Data can be accessed with :

my $ref = shift @items;

# print  'http://images.iwoot.com/thumbs/20qpuz_th
print $ref->{'SmallImageURL'};

Here you dereference $ref with ->, and then say that the referenced object is a hash, by using ->{..}.

You can do the same with each value of your array.
