If I show you a tomato and say "Italy" you will think of Tuscany fields under the sun, a juicy, tasty product, a rich spaghetti sauce, all the Italian culinary traditions. That's how Panzani, a French agro-industrial brand, sold its tomato sauces and pasta to millions of families after World War II.
I told you recently that one of the basic rules for a good User Experience (UX) on your website is to "delete your copy by half". I know it's hard to be concise. But one exercise to reach this important goal is to try and use 2 words. For example, one noun and one adjective. The result you want to achieve is to give way to the audience's imagination. The picture will tell them a lot; add 2 words to anchor it the way you want and leave the rest to the stories these words bring up in people's mind.
