In previous sections, you saw how you could manipulate the suffix of the image URL to display the same image in different sizes (if they exist on the Image server). There are some additional manipulations you can perform using the URL and achieve image effects that are not offered by Amazon Associates Web Service operations.
Discounts are often a sales driver for products. Amazon Associates Web Service can display discount icons by appropriately manipulating the image URL. For example, to add a 20% off icon, add "_PE20" (PE stands for "percent") to the URL right after the image identifier, as follows:
http://images.amazon.com/images/P/0976925524.01._PE20_SCMZZZZZZZ_.jpgThe following figures shows the addition of the discount icon.
Change the percent off by changing the numerical value. For example, to make the discount icon 30%, use _PE30.
