Why we should care

Displaying the source of the image may make it easier for users to get familiar with your brand and improve click-through rates from those already familiar with it.

If the carousel links directly to the image source — as opposed to the Images tab, which it currently does — then optimizing your images to be included in the carousel can be another source of traffic.

If this test gets implemented as a regular feature, it will also be another detail that differentiates Bing’s search results. Currently, both Bing and Google display image previews on their main results; however, sources are not displayed until the user clicks on a preview.
