Bought a new camera, mainly to sell items here, but the KB's of the photos are too large to post here. I have managed to crop a few photos down to where they will fit here, but I need to photograph some items where cropping would be of no use, or would not allow a full view of a larger item to be posted. Can the camera be adjusted to reduce the KB's of the photos? It's a Nikon S7000. And, is there a program loaded under Windows, etc., or one that can be downloaded, to decrease the KB's? I am not very computer literate, so "tech talk" won't help much. Thanks for any help.
