Improved Balance Between High-Res Images and Performance

Bringing high-resolution images over slow performing networks to mobile users has been an agonizing challenge. We finally have the right balance.

The Problem

Our apps pulls relevant images from millions of servers located throughout the world. Slow servers, slow wireless networks, and slow devices make this an interesting challenge.
  • Too many of the web servers are under-powered - unable to respond quickly to our requests. Many are located on slow hosting sites.
  • 3G as a transport can be highly constricting.
  • Slow devices are unable to display our animation in a timely fashion.
Thus, we've been forced to rely on low-resolution images stored on Google and Microsoft's fast server networks.

The Solution

Our engineers have managed to create a balance between high resolution images and performance.
  • If the high-resolution image is stored on an adequate server and network, then we show the best image.
  • If the image cannot be retrieved in a timely fashion, then we show Google or Microsoft's shrunken version of the image.
  • As more wireless networks evolve to 4G performance, our results will improve automatically.
Hope you enjoy the improvements. Select one of the apps below and try the new slide shows.
