First impressions matter, whether you’re on a first date, in a job interview, or just choosing new decorations for your house. Some of the first things you see when you visit someone’s profile or page on Facebook are the pictures. These pictures are an integral part of the Facebook experience, but sometimes they can be slow to download and display. This is especially true on low-connectivity or mobile networks, which often leave you staring at an empty gray box as you wait for images to download. This is a problem in developing markets such as India, where many people new to Facebook are primarily using 2G networks. Our engineering team took this on as a challenge: What could we design and build that would leave a much better first impression?
