Apologies in advance for my ignorance as I am new to Surface. On the start (or home) screen, there are a number of Apps shown. One is Photos. When playing around with the camera, I took three pictures (quality not very good ). I deleted the pictures and so no longer appear in the "Camera Roll" or anywhere else that I can see. However, the three pictures continue to "scroll" on the Start screen. How do I delete these photos from streaming on the Start screen? Thanks.
