for some reason i am unable to loop through all 100 products. i also am 
unable to use something like @output['products'][0]['images'] to select the 
image using image_tag. I can use ['products'][0]['name'] etc just not the 
images or looping. 

Could anyone help in what im doing wrong. I tried looping the outer 
elements first then the inner elements but failed. @output contains 100 
results from the api call from webhoseio. (i dont want to use the webhose 
gem im really trying to grasp an understanding of how to use other gems 
like httparty or rest-client.) 

the format was set to :json
