I didn't see a way to reply to the people who tried to help, except to just reply to the post. The camera-made photos on my hard drive always show perfectly on the screen, but photos on the internet are usually messed up, but some days they are good. When they are good, they are good all day. When they are bad, they are all (on the internet) bad, but some are worse than others. I think it is just some range of colors that are displayed as this bright mossy green, with other colors being displayed properly. The computer is pretty old (more than ten years) and no changes have been made in a long time. It just got to where it would do this sometimes and then got to where it would do it most of the time. I can't understand why it displays my resident pictures perfectly if it is the graphics card, but I can't think of anything else. The attached photo was copied from Facebook. I don't much want to start fixing things until I can learn what is broken.
