Easy 10 points! Help me elaborate this sentance?

A picture can lead one into wanting a product or even a human being. Your own photograph, Jessica, is an instance of playing with desire, since it is sweet and not without a certain allure. However, looking at a picture of an ice cream sundae can make one crave a sweet and I can never resist the ads that show shrimp well seasoned on rice (preferably saffron rice). I want to go right out an order a paella.
