Before spending money on images, spend money on a better quality product.
One of the maxims in product marketing is, "Sell the sizzle, not the steak." This means to focus on selling the emotional product attributes, such as the feeling ordinarily associated with the sound and smell of a steak cooking on the grill, instead of the actual steak itself. While it is understandable how this concept can be applied, American companies have gone overboard by spending millions of dollars advertising the "sizzle" of many products at the expense of improving product quality.
