Richard,
Win XP, working with Internet explorer. Thanks for the suggestions, but my point was that it has suddenly changed the way it saves image files. I can manually save JPEG files by typing a file name with a .jpg on the end, but I never had to do this before. I could just right click and it would save it as the original file name, and as the same as the file type, and not .BMP, which is now the only choice 'automatically'.
