On the idea of creating product images from the app and replacing the Internet to obtain the product images remotely

When I use a variety of e-commerce or apps, such as apps, the app constantly from the remote server to obtain a variety of product images. Can I cancel this way? Generated only by the app.

The app generates images, and the server provides the product description instructions. For example, when an app needs to display an Apple image, the server provides a simple product description directive: Apple. When the app gets to Apple's command, it automatically draws an apple image. In this way, the data transfer between the app and the server will have simple information such as simple description instructions.

Then the key issue shifted to the picture generation.
