Abstract: In general, the subject matter described in this disclosure can be embodied in methods, systems, and program products. A computing system receives, from a first computing device logged into a first user account, a request to view an image that was provided by a second user account. The computing system provides, for receipt by the first computing device, first information to cause the first computing device to present the image with an object in the image obscured. The computing system receives an indication that the first user account and the second user account interacted. The computing system provides, for receipt by the first computing device, second information to cause the first computing device to present the image with the particular object at the particular portion of the image unobscured.
