These frame corners are contained within a PowerPoint presentation that you download. Use these to make your pictures look stylish. You will find these frame corners in both black and white colors, and also filled with some solid colors, textures and gradients. Just copy and paste them as individual frame corners over your inserted pictures (or other slide objects). Start with placing them on the top-left corner of your pictures. For the remaining three corners, duplicate the existing frame corner, and place the duplicates on the other three corners, and rotate them as required.
