I insert an image into a powerpoint slide. It looks fine until I save, then
it displays a line border along one or more of the edges.

Images are JPEGS from stock photography. They are not resized, have no
borders or any other modification. This only happens with some of the images
in the library.

Cropping the image takes it away, although it will often return on the new
cropped edge.
